> Has the R3000 code been integrated into the 1.3.58 kernel yet?
Yes, I've got 1.3.59 with the R3000 stuff on my disk at home. The
R3000 stuff seems to be a bit "magic"; means though there is no visible
bug it somehow triggers another bug for the Acer making the keyboard
and floppy partially unusable for Acer. I suspect this might be the
same bug Stoned reported recently.

At least it sound like a reasonable place to poke around.

Though not all members of the R4000 family have the c0_count register.
This is also why Linux doesn't use it (yet).

There are NetBSD and MACH ports to DECstations. Probably the best reference
to get without asking DEC.
