clock rate too high?

Are we talking about the number gtf reports as pclk?

Although I didnot get my custom ModeLine for 1280x1024 75Hz working.

I did manage getting the on motherboard via chipset talking to the lcd
panel at 1280x1024 75Hz using FC4's gui config tools.  Confirmed by the
lcd onscreen info.

Which should be a pclk of around 138MHz, which is much higher than the
106MHz for the 1440x900 ModeLine.

Or am I totally confused?

Why PCI?  Why not AGP?
