There are probably no impossible things - some may be unthinkable but once
they are thought of, they can be done too. But this one thing may be
rather difficult (just my opinion).

How about porting kernel and gcc to your fp-cpu and use pci as a
kind of fast network-like interconnect? After loading a kernel into it
somehow, boot it with nfs root and run the rest from nfs server that would
be provided by a host Intel machine.

That would require less changes to a kernel, probably. A module for a
host, for example - some "pci-net". And port of a kernel to your fp-cpu
which should be easier than putting support for heterogenous
multiprocessors...
