Dell M4400 && Xorg-vesa && 1920x1200 res?

Hello,

I've a brand new Dell M4400 laptop running CURRENT; the nVidia
Corporation Quadro FX 770M
ship is currently not fully supported by the nouveau driver and I'm
bound to 'vesa' driver for that, at least for the moment. The resolution
of the laptop is normally 1920x1200, but 'vesa' seems not been willing to
use this res. even if the Xorg.0.log has lines saying that there is an
internal mode like that but not being used:

*Mode: 17d (1920x1200)
        ModeAttributes: 0x3bf
        WinAAttributes: 0x7
        ...

(II) VESA(0): Monitor0: Using default hsync range of 31.50-37.90 kHz
(II) VESA(0): Monitor0: Using default vrefresh range of 50.00-70.00 Hz

(II) VESA(0): Not using built-in mode "1920x1200" (no mode of this name)
...
(II) VESA(0): Not using built-in mode "1920x1200" (hsync out of range)

(--) VESA(0): Virtual size is 1280x720 (pitch 1280)
(**) VESA(0): *Built-in mode "1280x720"
(**) VESA(0): *Built-in mode "800x600"
(**) VESA(0): *Built-in mode "640x480"

and at the end it gives 1280x720 (which is not bad but fare away from
1920x1200). My Display section in xorg.conf has:

        SubSection "Display"
                Viewport   0 0
                Depth 24
                Modes "1920x1200" "1280x720"
        EndSubSection

Any idea how I could get 1920x1200 with the 'vesa' driver in Xorg 1.6?
I need that box urgently for my daily work...

Thanks
