Interesting Video Problem with ATI Radeon 9800 Pro (not a 3D accel based problem)

I just finished a fresh install of Gentoo Linux.

Basic system specs:
AMD Athlon 2500+
1.5GB of RAM
ATI Radeon 9800 Pro 128MB
SB Live!

Package versions:
Xorg-x11 version 6.8.2-r2
Gnome (light package in Gentoo) 2.10.1
ATI Radeon drivers version 8.14.13-r2

Here's my problem. Gnome/X is rendering really slowly. It's just not drawing as fast as it could. The fade after clicking "Log Out" in the Gnome menu is not a fade at all... it's like a slideshow. Loading up a fullscreen app shows a slow draw as well, and loading up a new website in Firefox shows the same speed problem.

Also, the first time I click on them, menus aren't quickly responsive. And of course, windows don't really just "appear" when I open them... I can actually see them draw. Dragging the gnome terminal around (with solid background color, no transparencies) results in an insane amount of tearing.

But here's the kicker... glxgears reports ~4000fps and TuxRacer is running like a bat out of hell at 1280x1024. Basic info from glxinfo shows that 3D acceleration is set up perfectly.

So... for the first time I have flawless 3D performance after a nearly fresh install... but the simple 2D performance of opening windows and webpages is noticably bad.

I'm totally at a loss here. Anyone have any ideas?

Well, I believe I've used up all my "auto bumps" so here's a little bump hoping someone has some idea of what might be wrong.

I've done a bit of research and haven't been able to come up with anything, except that I appear to not be alone in this problem, just... in a minority.
