Even the PCI SunGEM cards have the FORTH firmware stuff in their PCI
ROMs.  The FORTH firmware on the Sun or MAC machine, at boot time,
looks for the FORTH signature in the PCI ROMs of all the devices in
the machine, and executes whatever matches it finds.  The SunGEM PCI
card variants have this firmware, just like the motherboard variants
do.

I don't think a SunGEM chipset card or motherboard implementation ever
existed without the necessary FORTH firmware in the PCI ROM.  And,
certainly, no SunGEM was ever made with accompanying x86 style
firmware in the PCI ROM.

Hmmm... actually, I think I have a dual-function PCI card somewhere
that has a SunGEM and a Qlogic scsi controller.  If I can dig it up
I'll stick it into one of my x86 boxes and play with your patch :-)
