Do you happen to have a good reference for the io ports you mention? I
see them described on a number of Linux forums, but a canonical source
would be nice.

The loader only includes inb and outb for i386 (the non-UEFI loader is
32-bit for both i386 and amd64):
#ifdef __i386__
dictAppendWord(dp, "outb", ficlOutb, FW_DEFAULT);
dictAppendWord(dp, "inb", ficlInb, FW_DEFAULT);
#endif
We'd need to make these available in the 64-bit loader.efi, although
I'd really like to have MBP support be handled automatically in the
loader itself.
