I am having some trouble with bringing up my wireless. I am not new to Linux, so I'm not sure why I am having trouble. Maybe someone can point out my mistake.

I installed BT 4 R2 on an IBM ThinkPad R52. It's running an Intel Corporation PRO/Wireless 2915ABG [Calexico2] on-board wireless. I am not able to find my wireless card. LSPCI will show the model, but no wireless interfaces are available. Booting an Ubuntu live CD finds the card out of the box, so it doesn't seem to be a Linux kernel issue. I also have a Ralink RT2870/3070 card, which works great - no configuration necessary.

This is some possible relevant information in dmesg:

ipw2200 0000:04:02.0: PCI INT A -> GSI 21 (level, low) -> IRQ 21
ipw2200: Detected Intel PRO/Wireless 2915ABG Network Connection
ipw2200: ipw2200-bss.fw request_firmware failed: Reason -2
ipw2200: Unable to load firmware: -2
ipw2200: failed to register network device
ipw2200 0000:04:02.0: PCI INT A disabled
ipw2200: probe of 0000:04:02.0 failed with error -5
Any help would be appreciated.
