The init scripts of all distributions but SuSE handle this just fine
(mount -n). At least SuSE seems to mount the root fs rw from the start,
which causes all sorts of pain if you want to boot into a RedHat system
using the SuSE rescue disk. No idea how SuSE copes with readonly root fs.

Anyway, this wasn't the issue initially. It seems /proc/apm should be
doable on PPC for programs that don't use apmlib, and the apmlib glue code
takes care of the others.

Yeah, like Linux will never run on my old 4 MB Mac anyway.
