I think you should just use call32() and not do anything special.  I
don't see why you need a function table or any defines.

BTW, do you really need to be in 32bit mode, or can this just be done
in 16bit mode?

I'll need to at least use big real mode since the device addresses are at
0xfed40000 and will need to write data into ACPI tables.
