drm Q, kernel 2.6.28.6

[Gene Heskett]

In rebuilding the drm.ko and radeon.ko modules, I am seeing this warning go by 
in large numbers:

/usr/src/drm/linux-core/drm_compat.h:346:2: warning: #warning "init_mm is not 
available on this kernel!"

As this kernel is home brewed, like most I've been running for the last 10 
years, is there some specific option in the .config that I need to enable?

Thanks.
