Claude,

"man radeon" would be the place to look along with "man xorg.conf".  In
any case, these settings shouldn't be dangerous to your hardware.
AGPMode is simply the 1x,2x,4x,8x speeds you see on AGP card spec sheets
(and 8 isn't a valid parameter here).  My card ought to run at 8x if you
can believe the box, but it will only run at 2x (the "2") with the
radeon driver.  Since the changes worked and the frame rate was high
enough for my occasional dalliance with Tux, I didn't bother to look any
further.

HTH,

Karen
