OK, yeah, I'm at 2.8.20, and can't even update from the FC5
repositories (I'd have to go to at least FC6).

I installed FC5 off a co-worker's CD, and didn't realize just how
outdated it was.  I think I'll do a fresh install of FC8 and test
there (as well as with Ubuntu).

Unless I'm not the only one running such an outdated distro, it'd be
silly to support something so old.  Thanks for looking into it,
though!
