Bryan,

Thanks for the info and the offer to compile stuff.  I
think I have enough pieces to put togeather an old
socket 7 system.  I figure I can install NetBSD for
i386 on it.   From there it should be fairly easy to
compile stuff for the Mobile Pro.  With a little more
work I might be able to figure out how to compile
stuff from my linux system (Mandrake 9.2)

Interesting what you said about mipsel (MIPS little
endian) binaries.  I didn't realize that the
difference was so subtle.

Thanks again for the offer.  I am going to try to put
together my own solution, but if I get stuck I may
take you up on the offer.

Rafe
