The mace driver has some hallmarks of a half finshed project - not to slag
jmt, maybe he never saw the transmit timeouts... He's to be credited for
figuring out the PSC stuff, that should be the only difference to the
powermac MACE then. txdma and rxdma reset are implemented, the rest
should be similar to powermac.

Disk acting up? Pity we can't easily netboot a Mac without working disk
...

pmac_zilog should be a straightforward port (I looked at it while fixing
the Atari serial driver) but we'll have no end of trouble to get rid of
incoming characters now that the tty flip buffer can't be flushed from
interrupt context. Anyway, the mac serial I can help out with, having
hardware to test. The MACE driver I can only cook up a speculative patch.
