        This issue may very well be a KDE4 issue. I decided to load KDE3 
tonight to
triage the jilted system and, on a lark, recalled the glxgears issue so I
decided to test with glxgears. The differences were startling to say the least.
All I did was install KDE3 on the exact same machine and log into KDE3 and then
start glxgears; I was shocked at the differences in the frame rates for the
same hardware and with the desktop being the only difference. The KDE4 numbers
are above. Now,here are the frame rates from KDE3:

01:08 arete~> glxgears
31248 frames in 5.0 seconds = 6237.533 FPS
30700 frames in 5.0 seconds = 6139.998 FPS
29088 frames in 5.0 seconds = 5817.566 FPS
29807 frames in 5.0 seconds = 5953.829 FPS
29799 frames in 5.0 seconds = 5956.565 FPS
29687 frames in 5.0 seconds = 5930.866 FPS

        A full 30+% faster than the frame rates seen under KDE4
