I installed FC6 on a different PC and copied the root file system to a CF
card, from which the VIA C3 IPC boots.

Yes, that seems to be the reason. Problem is that I need glibc 2.5. If I
replace the Fedora glibc with the binaries from Debian Experimental, I get a
little farther in my boot process. It boots, but I can't login. So probably
all Fedora binaries can contain this illegal instruction.

Good idea, unfortunately, the Fedora installer doesn't work on this machine...

Thanks for that hint.

I'll find out :-)
Thanks,
