Is there a way to test at runtime if PMM works? If so maybe this can help?

I'll test later today with a git-version and post the pci-version.

I've been wondering of the manufactorer can do something about this
128kb-orom-limit? I'll explain to them what caused the problem as well as
why they cannot reproduce it at their side. On the other hand I have an
efi-bios which should be capable of overcomming the limitations of the old
pc-bios. Any ideas if and how the manufacturer can help (if they're willing
to do so, of course)?
