Personally I prefer to have as little fglrx options set as possible, as for me it seems to work best with most left with their default values.

This is what aticonfig does automatically, so I stick with the options provided there (see "aticonfig --help").
Currently these are (8.42.3 / X1400 with XOrg 7.2 on Gentoo):
This corresponds to the xorg.conf options "VideoOverlay", "OpenGLOverlay", "UseFastTLS" and "MaxGARTSize" being set. And thats all. Additionally I commented out my whole "Module"-Section, as the XOrg defaults work fine for me here, too.
aticonfig --overlay-type=Xv --tls=1 --max-gart-size=256
The only non-standard option is "XaaNoOffscreenPixmaps" set to "on" in my "Screen"-Section (IMHO this option does not apply to the "Device"-Section as stated elsewhere, see "man xorg.conf"). On my HW this prevents the infamous artifacts around the cursor and in the lower right corner from appearing.
