Someone might already have done it, I think someone has implemented a 6502 
core. I've got the Digilent Spartan-3 kit, there is a 6809 core I've tried 
on that which runs the Flex operating system. Some students have actually 
done an ARM implementation on an FPGA and made it available via the web, but 
ARM wasn't very happy about it, so it's difficult to get hold of.

Lots of free cores are available here:
