The SPARC graphics organization is not planning on porting the
semi-accelerated drivers for graphics like m64 that haven't been
sold in quite a while - they're concentrating on the more recent
cards. I'm running Xorg on my Ultra 10's onboard m64 right now,
but it's using a "dumb" frame buffer driver (wsfb) that just mmap's in
the correct amount of memory and sets values in it, without using any
acceleration functions provided by the hardware. I haven't actually
done performance tests to see how slow or fast it could be.
Xorg does have open source drivers for the ATI hardware that could
possibly be ported in the future by someone other than the SPARC
graphics organization (one of our engineers got it running on a PGX64
board, but that required use of /dev/xsvc, which we'd prefer to avoid
if possible).
