It appears that the first slot in the `mem' list (/memory's reg
property) is permanently empty (i.e. size 0) on my machine.  Could
some please build me a kernel that just skips the first slot
(i.e. just increment the frigging pointer) after both calls to
mem_regions() (in macppc/machdep.c and powerpc/pmap.c)?  (And then
upload the kernel and send me email?)

Please don't worry about doing this right at this moment.  I need the
kernel ASAFP.

Thanks.
