IBM Thinkpad: 1802: Unauthorized network card

Today i want to test an new wireless lan card in my notebook. I am using a Philips 802.11a/b card in my T40p. Because i think it would be nice to have also 802.11g support, i try upgrade an Intel Pro Wireless 2915ABG card.
After having some trouble to get a T7 screwdriver, thanks to Daniel Willmann, replacing the card was no problem. But after power on the machine again the BIOS told me something like: "ERROR 1802: Unauthorized network card is plugged in. Power off and remove the miniPCI network card."
After some googling i found some interesting sites an information:
http://www.paul.sladen.org/thinkpad-r31/wifi-card-pci-ids.html
http://www.srcf.ucam.org/~mjg59/thinkpad/wireless.html
http://www.ussg.iu.edu/hypermail/linux/kernel/0406.1/1048.html
After get the information, the whole story is fast to tell. Get sourcecode, compile, execute and it works. No more bootup error. Now compiling the modules and making the card running was the smallest problem. I wrote this blog entry over wireless lan with my new card running. :)
Some words about the bad idea from IBM to have a whitelist for MiniPCI cards in there BIOS. I bought my notebook because of the quality and linux friendly hardware. But restrict the user in which card he can use in his notebook is not the right way. I think there are a lot of cards are working in Thinkpads, and are not on the whitelist. MiniPCI is standard to have compatibility.

Thinkpad Dockingstation II and 20" TFT

Today my Thinkpad full dockingstation arrived at work. I also get an 20" TFT display with 1600x1200 resolution.
I read about problems with higher resolution then 1280x1024 on external DVI port at dockingstation. So i think it would take some time to get this thing working. But it was so much easier. :)
The only thing i had to do was adding 1600x1200 to the screen section in my xorg.conf file.
Next week i plan to test dock and undock functionality with ibm-acpi. If i find time i also do some test with different Thinkpad models, dockingstation and ibm-acpi to file up the compatibility matrix at project website. Too much work, too little time.
