When I tried the VESA driver on my system, the Xorg log file gave a list 
of "Supported VESA VIdeo Modes" which includes:

(II) VESA(0): 720x400 at 70Hz
(II) VESA(0): 640x480 at 60Hz
(II) VESA(0): 640x480 at 67Hz
(II) VESA(0): 640x480 at 72Hz
(II) VESA(0): 640x480 at 75Hz
(II) VESA(0): 800x600 at 56Hz
(II) VESA(0): 800x600 at 60Hz
(II) VESA(0): 800x600 at 72Hz
(II) VESA(0): 800x600 at 75Hz
(II) VESA(0): 832x624 at 75Hz
(II) VESA(0): 1024x768 at 60Hz
(II) VESA(0): 1024x768 at 70Hz
(II) VESA(0): 1024x768 at 75Hz
(II) VESA(0): 1280x1024 at 75Hz
(II) VESA(0): 1152x870 at 75Hz

Does yours include such a list?  If so, is 1280x800 on it?
