ext3 was what my filesystem WAS.
I gave up last night, backed up my /home, reinstalled Linux, and went from there. I had to re-do my 3dfx, java, and a few other tweaks, but it went very smoothly. And as I'm still learning, each reinstall is a good exercise for me.
Now I have a 1 gig /root, 500 mb swap, 30 gig /usr, and 48 gig /home.
Thanks for trying to help. The problem was too weird for me to want to deal with it anymore. Something went wrong with the KDE Diskdrake, methinks.
