The only fix would be fixing the vesa bios of the card. If that resolution doesn't work, it means that the vesa BIOS doesn't report it. So it's either someone writes a native (non vesa) driver or someone fixes the bios.
Dunno if this could be done with this video BIOS specifically but some video BIOS can be patched by software (ATI AtomBIOS, for example) to include the missing resolutions). Note I am not talking about a firmware update.
