title="RESOLVED FIXED - Maximizing glxgears -> texture_desc_init: The buffer is not large enough"

Running -git ati (856583dbca9) and maximizing glxgears, the DDX gives too small
a buffer to Mesa:
r300: I got a pre-allocated buffer to use it as a texture storage, but the
buffer is too small. I'll use the buffer anyway, because I can't crash here,
but it's dangerous. This can be a DDX bug. Got: 5083136B, Need: 5087232B, Info:
r300: texture_desc_init: Macro: NO, Micro: YES, Pitch: 1472, Dim: 1438x863x1,
LastLevel: 0, Size: 5087232, Format: x8z24_unorm</pre>
