How high does an Intel Q35 go?

Hello X developers...

I'm pondering the featureset of an Intel DQ35JO board.
This one comes with DVI _and_ VGA onboard connectors.

Manual[1] on pages 16-17:

Display
  Up to 2048 x 1536 at 75 Hz refresh (QXGA)
  Dual independent display support
DVI
  The maximum supported resolution is 1600 x 1200 at 60 Hz refresh.


My questions...
...is it possible to run DVI at 1920x1200 with
a reduced blanking modeline, ignoring what the manual
suggests? Anyone done this with a Q35?
...is it even possible to run DVI+VGA dualhead
at 2x 1920x1200?


Further, according to the table:

DVI Port Status
  PCI Express x16 Connector                          DVI Port Status
  No add-in card installed                           Enabled
  Non-video PCI Express x1 add-in card installed     Enabled
  PCI Express x4, x8, or x16 add-in card installed   Disabled
  ADD2 or MEC card installed                         Disabled

I understand it is not possible to convert the 2nd VGA into a DVI
by adding a ADD2 card and get 2xDVI, instead one would need
a ADD2 card with 2xDVI out? (unobtainable?)


Thanks for your wisdom,
Martin
