Check out my page about X on the Dell C400:

Your machine has exactly the same problem (as has the Asus
L1 series).  Blame Intel for not releasing the programming
specs to the chipset.

Only way to fix that problem at the moment is to reverse
engineer the mode set code in the Video BIOS, which is a bit
tedious (but maybe I get around to it eventually...)

Cheers,
Manuel

PS: Who knows, maybe they get a cut from the sales of Xi
    Graphics' X server, which runs fine on the chipset (so
    obviously it also circumvents the Video BIOS).

PPS: If anybody has some good friends at Intel, let me know ;-)
