drivers/built-in.o, cmpxchg, 2.6.1-mm5 and make-kpkg --revision

[Joseph Jones <joe@bumpycarrot.cjb.net>]

Having heard of people having problems with --append to version and 2.6, 
I decided to try with --revision. However, I get undefined references to 
cmpxchg in functions tdfx_lock_transfer, tdfx_lock_take, tdfx_lock_free, 
tdfx_notifier, radeon_lock_take. I then get error 1 (something to do 
with .tmp_vmlinux1 and error 2 ater leaving the linux-2.6.1 directory.

Any help would be greatly appreciated. I want so badly to get my 
nforce's onboard NIC working properly.
