The problem is that the imageWidth is set to zero, so when an application tries
to detect a useable DGA mode, these modes are skipped (assuming the application
checks the available widths and heights). I also submitted the same bug report
to the XFree86 devs, and I believe they fixed it in a more general manner by
clamping the co-ords to 16 bit values in "Xext/xf86dga2.c"
