Binary package hint: xserver-xorg-video-intel

The X intel driver in current intrepid (2:2.4.1-1ubuntu10.3) and in jaunty alpha 5 (2:2.6.1-1ubuntu3) does not correctly discover and initialize the 2nd DVI port on a dual-dvi ADD2 card. The card is a Wintec Pegasus ADD2 card:

Only TMDS-1 is detected and initialized. The issue is the same as reported in:

Bug 19770: Q965 dual-head DVI with ADD2 2nd panel can't be found

I applied a modified version of the patch in comment #22 to the 2:2.4.1-1ubuntu10.3 driver in intrepid, and it
resolved the issue fine. Note the issue also exists in jaunty alpha5.
