Pays never to throw anything out ....
Found a couple of old configs on my Gentoo desktop - 2.6.11 has
both skge and sk98lin as kernel options.
If you have the config available under FC (dunno, never used it), try the following commands
grep -i skge config-file
grep -i sk98lin config-file
As bulliver said, you might be up for a kernel compile depending on the results.
