Raja's already using the accelerated driver, but I think the following setting (from savage(4)) might also be needed, in addition to the modelines: Option "UseBIOS" "boolean" Enable or disable use of the video BIOS to change modes. Ordinarily, the savage driver tries to use the video BIOS to do mode switches. This generally produces the best results with the mobile chips (/MX and /IX), since the BIOS knows how to handle the critical but unusual timing requirements of the various LCD panels supported by the chip. To do this, the driver searches through the BIOS mode list, looking for the mode which most closely matches the xorg.conf mode line. Some purists find this scheme objectionable. If you would rather have the savage driver use your mode line timing exactly, turn off the UseBios option. Note: Use of the BIOS is required for dualhead operation. Default: on (use the BIOS). Raja, can you try experimenting with this setting?
