Thanks, Bruce. That seems to be the most direct way to go. The card is 
both "wireless" and "bluetooth" and I'm not sure which driver is which 
in the kernel configuration. What is apparently the firmware file, the 
rt3290.bin the kernel message referenced does not exist either on my LFS 
or my Ubuntu partition. I'm thinking that I'm going to have to build a 
module, but wireless-tools should be able to help me out. I had 
forgotten about it. I didn't want to have to guess at one configuration 
option, reconfigure the kernel, fail to boot and need to reconfigure again.

Thanks again.
