Warning: the T42 BIOS checks the hardware id of any internal wireless card and only accepts the Lenovo version of the card. So for instance you have to buy the Intel Wifi 2200BG card from Lenovo for it to work in your T42.
I think you can order the card as a spare part online from Lenovo using the FRU number in the hardware maintenance manual.
The only alternative is to get a modded version of BIOS that has patched the test for approved cards, see here.
