GL_MAX_TEXTURE_SIZE = 2048

xserver-xorg-core                 1.3.0.0.dfsg-12ubuntu4feisty 
xserver-xorg-dev                  1.3.0.0.dfsg-12ubuntu3feisty1

from Trevino's repositories. AFAIK this is a 1.3 server with some 
enhancements from 1.3.99. I haven't gotten around to building the 
xserver myself just yet...
