Two questions:

1) Does the MOBILITY version of the Radeon 9700 even support
    FSAA?  I know the mobility chipsets have quite a few limitations
    compared to the regular 9700.

2) How much graphics memory do you have?  Turning on FSAA consumes
    a LOT of graphics RAM - especially at higher screen resolutions.
    Does FSAA turn on when you set the screen size to something
    really tiny (like 640x480) ?
