On my Intel imac, /sys/firmware/efi/systab is the following:
ACPI20=0x1fefd014
ACPI=0x1fefd000
SMBIOS=0x9fec9000
if I have a kernel with a 2:2 user/kernel split, and
SMBIOS=0x5fec9000
if I have a kernel with a 3:1 split. The correct value is 0x1fec9000,
which is what the kernel prints at boot time. The following trivial
patch seems to fix things.
