I can confirm this bug with an Intel G965 X3000 GMA. I'm using xorg- server-core-1.1.1-0ubuntu13 and linux-2.6.20-6-generic. My architecture is AMD64.
A backtrace from /var/log/Xorg.0.log.old is similar to that of the original reporter: Backtrace: 0: /usr/X11R6/bin/X(xf86SigHandler+0x71) [0x487521] 1: /lib/libc.so.6 [0x2b9400cdbd40] 2: /usr/lib/xorg/modules/extensions/libGLcore.so(_mesa_update_draw_buffer_bounds+0x59) [0x2b94039bf5e9] 3: /usr/lib/xorg/modules/extensions/libGLcore.so [0x2b9403ada09d] 4: /usr/lib/xorg/modules/extensions/libglx.so [0x2b940208683b] 5: /usr/X11R6/bin/X(compPositionWindow+0x62) [0x550382] 6: /usr/X11R6/bin/X(ResizeChildrenWinSize+0x1bb) [0x43d77b] 7: /usr/X11R6/bin/X(miSlideAndSizeWindow+0x1af) [0x4e129f] 8: /usr/X11R6/bin/X(compResizeWindow+0xad) [0x55119d] 9: /usr/X11R6/bin/X(ConfigureWindow+0xb08) [0x43d238] 10: /usr/X11R6/bin/X(ProcConfigureWindow+0x96) [0x44e5d6] 11: /usr/X11R6/bin/X(Dispatch+0x1ba) [0x44ed4a] 12: /usr/X11R6/bin/X(main+0x455) [0x4379d5] 13: /lib/libc.so.6(__libc_start_main+0xf4) [0x2b9400cc88e4] 14: /usr/X11R6/bin/X(FontFileCompleteXLFD+0x231) [0x436cd9] Fatal server error: Caught signal 11.
