Great! I did test that FC8 with a Fedora kernel will see and use the 
floppy. Even found a floppy to use. Now I have to figure out why I have 
a floppy with a gzipped ext2 filesystem on it. :-(
Doesn't appear to be bootable, I thought it might be SYSLINUX for an old 
system which couldn't boot from CD or USB, but that doesn't seem to be 
the case.

Anyway, glad the problem went away.
