[Openchrome-users] CX700 800x480 mode

CX700 800x480 mode
Trying to set up openchrome to produce 800x480 with a CX700 on an EPIA PX10000G. For some reason, I can only get it to output 640x480 with the 800 pixels squashed into 640. The Xorg log suggests that it considers 800x480 to be a valid mode:
(II) CHROME(0): ViaValidMode: Validating 800x480 (31500)
(II) CHROME(0): ViaModePrimaryVGAValid
folllowed by no error messages, then after a bunch of modes that are discarded as invalid:
(II) CHROME(0): ViaValidMode: Validating 800x480 (31500)
(II) CHROME(0): ViaModePrimaryVGAValid
(II) CHROME(0): ViaValidMode: Validating 640x480 (25175)
(II) CHROME(0): ViaModePrimaryVGAValid
(**) CHROME(0): Virtual size is 800x480 (pitch 800)
(**) CHROME(0): *Mode "800x480": 31.5 MHz (scaled from 0.0 MHz), 31.5 kHz, 60.0 Hz
(II) CHROME(0): Modeline "800x480"x60.0   31.50  800 848 928 1000  480 498 501 525 -hsync -vsync (31.5 kHz)
(**) CHROME(0):  Default mode "640x480": 25.2 MHz (scaled from 0.0 MHz), 31.5 kHz, 59.9 Hz
(II) CHROME(0): Modeline "640x480"x59.9   25.18  640 656 752 800  480 490 492 525 -hsync -vsync (31.5 kHz)

Any ideas?

Thanks,
