This change is in response to Dirk Porezag's request
to add compat_ioctl so that a 64bit mga_vid can be
called from 32bit applications.

This change is a bit crittical as i changed the locking system
from BKL to spin_locks. And because i don't have an SMP system
on which i can test this (on single cpu/core systems, spin
locks become no-ops), i'd like to ask the people with
SMP/multi core machines to test this patch and report back
any problems.

Thanks
