(bpp / 8) * hr * vr <= ram
with: bpp -- colour depth
hr -- horizontal resolution
vr -- vertical resolution
ram -- video card memory
I think X needs a little additional memory for fonts and pixmaps.

The theoretical maximum at 16 bit would be something like 836x627,
1180x885 at 8 bit, provided you want a 4x3 display ratio. See the
XFree86-VideoTimings-HOWTO for additional information.
