I have only Macs, but I still haven't gotten any of them updated

with the current SCSI driver that I don't do anything more than
try out kernels with a simple root filesystem. My other older
systems are mostly packed away.
Indeed, poor IIfx, mine is a dedicated linux box, meaning that the mac
partition is only used to boot linux, still the about 50-60 K/s you get
from the HD scare you away. Still I have hopes in the 2.6 kernels
I had a driver partially written that tried to use the DMA engine, but
it never really worked quite right. The DMA would transfer the data
(I checked the buffer in memory and compared it to disk) but the chip
never actually sent the interrupt to notify the end of transfer. It's
not on top of my list, but I hope to get back to that at some point.
We should be able to max out the sort of old hard drive that would
have come with such a system by using real DMA.
