Thanks Jon. I'm still struggling with this rt73.bin issue. My 2.6.24 
Kconfig presents options slightly different from what you describe 
below. I've tried a few different settings and I placed the rt73.bin you 
sent me under /lib/firmware.

I'm still getting the "failure to load rt73.bin" error on "ifconfig 
wlan0 up".

my "generic" Kconfig options read as follows. I'm not sure if/what 
option maps to, "include in-kernel firmware blobs in kernel binary"

Could this be a udev issue?

(/sbin/hotplug) path to uevent helper
? ? [*] Select only drivers that don't need compile-time external firmware
? ? [ ] Prevent firmware from being built
? ? {*} Userspace firmware loading support
? ? [ ] Driver Core verbose debug messages
? ? [ ] Managed device resources verbose debug messages

I'll keep trying different things, but if you can provide additional 
guidance I will appreciate it very much. Thanks again.
