BIOS 2.11
With 4GB of the machines is not able to use the upper memory (PCI space)
2 GB RAM installed (Original IBM and still Cheap. They are covered by carepack 3-yr warranty).

1.2 Distribution

1.3 Unlock UMTS (WWAN) Card

Call IBM within 30 days after purchase, tell them the IMEI, say "Yes, I want!" and you get an unlock code. You can fire it via minicom/screen, but in some rare cases (such as mine) you need a windows based unlocker tool (MEPErase) from them. The tool is originally made my the manufacturer of the UMTS card: Sierra Wireless. This only works with native Windows as it directly accesses the HW. My tries via Wine and KVM were not successfull. Happy Windows Re-Installing ;/
The card works fine with current linux kernels.

1.4 e1000 checksum error modprobe e1000 eeprom_bad_csum_allow=1 or use lenovo's script to fix the hardware (better way IMO). Run this thing once:

1.5 Backlight video (garbles acpi-backlight button FN PGUP/PGDOWN)

1.6 ACPI Use: acpid, acpi-support, powersaved (powernowd didn't scale the freqency down!)

1.7 Power consumption

KThinkBat shows current power usage in watt. Very comfortable. It access tp_smapi if installed, so it's somewhat more acurate than doing so via acpi (Klaptop and Kpowersave do so ...)
Kthinkbat must be manually installed (uses tp_smapi if installed, so better)
With the standard 4-cell bat, my max runtime is around 2:20 (using WLAN!)
/etc/rc.local: add "ethtool -s eth0 wol d" and "iwpriv eth1 set_power 9"

1.8 Suspend/Resume

Works with 2.6.22, but after resume LCD backlight stays off. No way to reactivate it yet. :(
module kvm / kvm-intel prevent resume, unload them before suspend
ipw3945 is not unloadable unitl to also stop the userspace daemon. recommend: switch to iwl3945 instead.
iwl3945 still, doesnt solve the problem, as (k)ubuntu ships on outdated version
switched back to ipw3945. Found out that it can be unloaded via "modprobe -r ipw3945", as there there is a snippet shipped in modprobe.d, that unload the regulatory/userspace daemon of ipw3945
still dont know how powersaved can be made to use modprobe -r instead of rmmod
To reactive X backlight after resume, configure powersaved to "switch console before suspend". Drawback: The text consoles dont come back after resume.
Patch for powersaved to unload ipw3945: https://bugzilla.novell.com/attachment.cgi?id=101724&action=diff

1.9 HDAPS

hdapsd shipped with (k)ubuntu
currently exploring khdapsmonitor ( http://www.kde-apps.org/content/show.php/khdapsmonitor?content=41710 )
or: khdapsmon ( http://de.kde-apps.org/content/show.php/khdapsmon?content=34134 )
To Freeze the disk(s) in case of emergency you need the "queueprotect patch". This needs to rebuild the kernel completely as the patch is not a module and is not included in Gutsy. Argh.

1.10 ipw3945 vs. iwl3945

Standard is ipw3945
Blacklist is with echo "blacklist ipw3945" >> /etc/modprode.d/local
Then you can try mpdprobe iwl3945 instead
Attention! Maye you need to remove the /etc/udev/rules.d/70-persistent-net.rules

1.11 CPU Microcode

apt-get install microcode.ctl
Put intel-microcode.dat into /usr/share/misc/ . Download the file from http://www.urbanmyth.org/microcode/ucode/ e.g. http://www.urbanmyth.org/microcode/ucode/microcode-20070907.dat.bz2 .
