Jon,

Don't know that Linux has been pushed down into FPGA's (yet), not enough
horsepower in them I think.  

Here is at least a partial listing of uC:

One mfgr. I think is interesting is NEC:

1545 MIPS/watt, however its definitely not an FPGA :)

There may be other uC whose instruction set is only partially supported at
this point.
