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?
