Just tested arkfb and s3fb and they seem to still work fine (on x86)
with these changes.
Hmm, that's odd. The exact same driver with the updates crashes on
sparc hardware. So far, I've not been able to figure out why it does.
We know why it does, because sparc systems do not initialize the VGA
hardware in the BIOS the way a PC will.

That's the whole gist of the most recent thread we had where we were
trying to diagnose your crashes.

We simply haven't figured out the magic that will get this to work.

So it's perfectly fine and expected that platforms where these drivers
worked before, still work fine.
OK, I'd forgotten that the VGA hardware needs initialising.
Playing with (at least) S3 initialization is on my todo list.
