XFree86 limiting dot-clock to 125MHz when chip goes to 230MHz

["Daniel B." <dsb@smart.net>]

My X server seems to be limiting the video modes to a dot-clock to
125MHz even though video adapter's chip goes to 230MHz.

The adapter is an ATI Radeon Rage XL PCI card.  The chip's dot-clock
goes to 230 MHz (per
http://ati.amd.com/products/server/ragexl/features.html ).

My X server is Sarge's xserver-xfree86 4.3.0.dfsg.1-14sarge5.

Is there some configuration to set to tell X that the chip can
handle 230MHz?



I just upgraded from XFree36 3.3.6 (package xserver-svga) and a
Diamond Viper 330 / vNidia RIVA TNT2.  That X server allowed at least
202 MHz on that card without any special configuration.


Thanks,
Daniel
