For what it's worth: I just changed the line

                wdc->sc_status = status = inb(iobase+wd_altsts);

from wd.c to use wd_status i.s.o. wd_altsts, and things seem
to work fine now (am typing this while running X with the new kernel
I just booted). But.. there probably was a reason to use wd_altsts
there, so this is probably not the right fix.
