gnome-terminal kerning problem after FC6 upgrade

[fedora-list at epperson.homelinux.net]

Did a yum update to FC6 from FC5 on my Latitude D600 laptop, and the fonts
got all weird.  My Squirrelmail page had big blocky serifed fonts, for
instance, and saw other similar things in Firefox elsewhere.  Restored
/etc/fonts from FC5 and got rid of that issue, but I still have very
strange kerning in gnome-terminal.  For instance, when I type an "mv"
command, it looks more like "nv", and in a "ls" listing, some file names
are squashed like that, others are oddly spaced out.

Have poked around and found all kinds of references to fiddling with
smoothing, font rendering, and hinting in gnome-font-properties, but can't
seem to fix this.  Embarrassing part is that I'm a RHEL-certified Linux
systems engineer, but I do servers mostly running at runlevel 3, so don't
know that much about X and what rides on top of it.

If it's a FAQ, just point me in the right place.  Thanks.
