What's the firmware version?  If it's the new 1.103 firmware from CVS
then it's known to have some problems.  Please use older firmware from
http://thekelleys.org.uk/atmel/atmel_firmware.tar.gz for now.  Sorry for
the inconvenience.  I hope to fix it soon.

There is no at76c503_rfmd in CVS.  You must be using some older version
from CVS.  Loading more than one module at once is undocumented, and I
wouldn't do it.

It might.  It's better to compile everything with the same compiler, or
at least with compilers with the same minor and major versions.
