A more practical project if you really want to upgrade your mainboard is to look at getting a StrongARM CPU emulator like QEMU to work and then make a "virtual" empeg that actually runs on x86 systems. Then you could use a mini-itx board or something like that and run the player software on it. Then you could run "virtual" Empegs on standard x86 hardware- that would be way cool. Of course most of these virtual Empegs would probably be home-bound systems because even mini-itx is too big for a lot of dashes. I'm not sure what the empeg gods would think about someone emulating it either...
