- Kernel image patched and configured for improved speedstep support (ACPI bios only reports 600 and 1500 Mhz): Read about the applied patches below
- acerhk module, needed to enable the wlan switch and hotkeys
- IPW2200 modules, native drivers for the centrino IPW2200BG wlan chipset; get firmware files from the project homepage
- fglrx modules compiled for use with patched kernel, get additional packages from linked URL for accelerated OpenGL support
Since the latest release, the ipw2200 driver does not include the ieee802.11 framework anymore, it has been moved to a seperate package which is available here as well.
Note that the location of the fglrx repository has changed!
Since I'm not familiar with the creation of debian module packages, they might be a bit ugly, but do work quite fine. The debianized sources are available here. Check this good site for additional information about Debian on the TM292.
Questions & Answers
How do I install the packages?
- add the section described below to your /etc/apt/sources.list
- apt-get update
- apt-get install
- install additional packages for your ATI Mobility Radeon
- check your XFree config; you can take a look at my /etc/X11/XF86Config-4 here
- download the firmware file for you ipw2200 wlan chipset
- edit /etc/modprobe.conf (see below) and add "acerhk" to /etc/modules
- reboot into your new kernel
What patches are included in the kernel image?
- Software Suspend 2 allows you to suspend your system by writing the RAM content to a swap partition, and later resume where you left. I'm preparing a tutorial about this issue at the moment.
- cpufreq-speedstep-dothan-3.patch equips the kernel with own steedstep tables for a dothan cpu. Acer somehow screwed up the ACPI bios, which will only report 600 and 1500 Mhz as valid frequencies, although 800, 1000, and 1200 Mhz are possible as well.
This patch is not completely undisputed, since there are still some unclear facts about the dothan voltage levels. See the discussion yourself here, and consider this a warning. Don't hold me responsible if your system catches fire.
How do I enable the framebuffer console?
To enable the framebufffer console at the correct resolution, add the statement "video=radeonfb:off vga=834" to you bootloader setup, see below for an excerpt from my grub configuration.
"Software Suspend 2" is a kernel patch that allows you to suspend your system by saving the memory content into a swap partition and powering down. When booting the system again, the kernel recognizes the frozen image, und restores he former state of the notebook. The use of Software Suspend requires some prerequisites:
- a running kernel with "Software Suspend 2" patched in, e.g. the kernel-image-220.127.116.11-tm292 available here
- a swap partition (swap files do not work) large enough to fit your RAM content into
- the debian package hibernate, which supplies a script that takes care of nasty hard- and software during suspension.
Once the kernel is running, you have to modify your bootloader (lilo or grub, preferred the later) to include the additional commandline statement "resume2=swap:/dev/hda6", where /dev/hda6 is the swap partition you wish to resume to. However, the ATI drivers are breaking Software Suspend, so you have to quit X11 before hibernating your notebook: My hibernate.conf does this automatically by shutting down gdm, it as well restores acpi and acerhk drivers after resume. Just copy it to /etc/hibernate/. If you want to suspend the system, just su to root and enter "hibernate".
If you do not need DRI and OpenGL acceleration, you can use the open source "radeon" driver. Software Suspend 2 works fine with this driver, even without quitting X11. Just replace the driver "fglrx" with "radeon" in you XF86Config-4, and remove "gdm" from the "RestartServices" line of "hibernate.conf". If you want to switch between the two configurations, use the "switch-xconfig.sh" script.
