So far we don't have a real running-from-ROM option for the C code as
we started copying the code segment along with the data segment to
RAM, a while ago, when I reduced the skew between Ollies boot from DOC
code and the rest of LinuxBIOS.  

I have some trouble seeing where running-from-ROM is an issue when it
only happens at boot time.  But except for the problem of maintaining
very divergent code paths I have nothing against it.
