OK, one question, what exactly do you mean:
- PC motherboard with INTEL/AMD x86 and emulator somewere in bios on flash or whatever
- MC68060 board like the milan, hades, bla
- Coldfire based board
- PPC based board (just like amiga) like pegasos offers?
OK, you write "PC mainboard", but
Surley you can't honestly mean you want to put a motorola CPU in a PC mainboard cause that sureley isn't possible (and motorola sadly doesn't make a 2GHz cpu at the time snif ;,-( anyway)
