Maximum Resolution for FSAA in X800 RADEON?

[CHANGE USERNAME TO westes]

What is the maximum resolution at which FSAA will work in the RADEON X
series cards? In the RADEON 9800 series it is 1600x1200. For HDTV
support I suspect that this number had to increase to at least 1920x1200.
Strangely, I don't find the number in the X800 data sheets on the ATI site.

Highest possible FSAA resolution depends on framebuffer footprint.

e.g. 1920 x 1200 x 4 (32-bit) x 2 (double-buffered) = 18.4 MB

Under 6x FSAA it swells to 111 MB, which doesn't fit on 128 MB cards because
of the other stuff like shader instructions and the Z-buffer that also share
the space. Thus, the drivers may have been hard-coded to limit AA to
1600x1200 under all modes.
