I think one of the bugs I'm getting on video switching is going to require me
to disable all interrupts while I swap modes and load colors. What's the
function that does this? More importantly, what's the function that turns
interrupts back on :)

I know everbody was groaning about this sort of code last month during that
clock tick loss discussion but I think this is genuinely necessary. :)
Basically, any RBV-style system generally places certain SCSI duties on the same
chip as the internal video. I have a feeling that most of the time I can
get away with fiddling with internal video but once in a while intvid and
SCSI seem to be butting heads with each other.

Thanks.
