Yeah, but you'll be limited to 4096 pixels -- Mesa can't go beyond that.

Here's what I tried:

diff --git a/src/mesa/drivers/dri/i965/brw_context.c b/src/mesa/drivers/dri/i965/brw_c!

    ctx->Const.MaxTextureUnits = BRW_MAX_TEX_UNIT;

 /*    ctx->Const.MaxNativeVertexProgramTemps = 32; */

I suspect the 3DTextureLevels and CubeTextureLevels need frobbing as
well, but I didn't try to figure out what the right values might be.
