All drivers that use DMA need modifications for MIPS systems, so most, if
not all of the ISA/EISA drivers should currently not usable.

The PC speaker driver should probably work ;-)

The machine will definately make a nice job in that.  People have already
reported to me that they're quite satisfied with the Magnum's performance
for mp3 encoding as well.  (I wonder what software they use or is there
already a free mp3 encoder available as source?)

I've never seen a processor like that before.  The only thing I bet on is
that this processor is buggy like shit.
