So, the base of your kenrel is mainline, but some drivers is from 11.05. 
That's why you're facing the mismatch.

Ofcourse, but I don't hope it's easy task. You can try to resolve one 
build error at a time, and try to change Makefiles and #includes to make 
sure you have what you need inside the package itself.

I don't know if it's easier to change kernel or MM package.
