description:
Remove OFB_ENABLE_CACHE
from <macallan>
"it is outdated, genfb and friends don't need or use it, and it makes no sense
on accelerated drivers either. It tries to BAT-map the framebuffer cacheable,
which works on most macs but makes a few models lock up. Genfb doesn't have that
problem and is faster too."
