Grr, yet another annoying quirks on Apple OF.
I'll revert MSDOSFS size to 8MB for now.

Hmm, cmdide0 is on pci1 over PCI-PCI bridge, and it looks
src/sys/arch/powerpc/oea/ofw_autoconf.c::device_register()
doesn't handle OFW bootpath which contains PCI-PCI bridge properly.

I'm not sure how OF spec defines such device node paths,
but I'll check how we should parse it.
