Similar issues with radeon (RV200). At least ColorTiling gets disabled.
(II) RADEON(0): Color tiling enabled by default
(WW) RADEON(0): Requested desktop size exceeds surface limts for tiling,
ColorTiling disabled
Option "ColorTiling" "boolean"
Frame buffer can be addressed either in linear or tiled mode.
Tiled mode can provide significant performance benefits with 3D
applications, for 2D it shouldn't matter much. Tiling will be
disabled if the virtual x resolution exceeds 2048 (3968 for R300
and above), [...]
Possibly we can live with that or use 'Virtual 3840 1200' instead, which
covers a 1920x1200 laptop panel + a 1920x1200 external display. Still no
ColorTiling for Radeon < R300 though.
