Would this be one of the things solved/cleaned up by seperating ide-pmac.c
and the CONFIG option for it into generic enable IDE stuff and a driver
for the builtin IDE on some machines?  Last I tried, I needed to enable
both cmd646 and ide-pmac on myy blue&white (trying to do this is on my
todo list, someplace.. :))
