Tried as you suggested.  Not sure what went wrong.  It starts out OK, then 
errors out:

$ make -C /usr/src/kernels/$(uname -r) M=$PWD modulesmake: Entering directory

I have the 2.6.35.11-83.fc14 kernel-devel installed and mt20xx.h is in the 
/usr/src/kernels/2.6.35.11-83.fc14.i686 path, so I'm not sure why make cannot 
find it.

Sorry to be such a pain.  Like I said before, I'm not a big kernel compiler.
