I know the Horiz and Ver freq settings already. I set them manually... nad they are not teh source of teh problem... as far as I know... the problem now is the GL "speed"... not the fact that the refresh frequencies are off.
Just trying beeing systematic ...
Fair enough :-) We've done a lot more tinkering... and oddly enough after re-doing the exact same steps for the 97th time (removing the drivers with rpm -e, adding in the drivers again with rpm -ivh), we seem to have got some kind of result. GL is working at the moment - why I can't say, and I dont' know that I can even duplicate it again. We haven't checked to see if it'll survive a restart of X or a full system restart yet. Kind of afraid to do so since it's taken almost full time fighting with the stupid video card since Saturday evening to get this far. I'm not convinced that this state (working GL) will remain for long... and the really annoying thing is that we didn't do anythign differnt to the previous 96 times we tried to get it working..... very puzzled by the whole mess.
