If you can get a 16Mbit EEPROM you can certainly fit a tiny boot manager
(that will select your boot devices and load the necessary drive) and a 
working linux kernel (or a minimal Hurd).

if you can write a recompiler, sure. However, the more registers, the more
efforts your recompiler will have to do : it will have to track data dependencies
with a much much wider window (if you consider our 64 registers).
If you don't write self-modifying Forth code, it should work, then ;-)
