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?
