What about bitplane modes? Okay, that's really sick ;-)
(When I first assembled the machine I'm now working on I didn't have
the right video card, so I put in an old, unsupported VGA. Yes I got
it to work with the vga16 driver and even in a reasonable resolution,
but it is flabbergasting how slow a K6/233 can get with the "right"
peripherals ;-)

OK, ioctls are suboptimal for various reasons, but MMIO access to the
hardware still has a stability risk, at least with poorly designed
VGAs which seem to be the majority. :-(
