The vesa driver asks the BIOS to chose a display mode and
the BIOS keeps a list of possible modes. I have seen several
systems, all notebooks, where the vesa bios did not list
all possible modes, and this includes even the native resolution
of the display.

If you can't hack around this (like for the Intel chipset) you
need a driver that talks to the hardware directly. For older
ATI graphics cards, that shouldn't be a problem.
