Adds a quirk for the HP Compaq nx6110

Output of lspci -vvnn | grep -A1 "VGA compat":

00:02.0 VGA compatible controller [0300]: Intel Corporation Mobile 915GM/GMS/910GML Express Graphics Controller [8086:2592](rev 03)
 Subsystem: Hewlett-Packard Company Device [103c:099c]

Laptop: HP Compaq nx6110

Output of xrandr before changing xorg.conf:

Screen 0: minimum 320 x 200, current 1024 x 768, maximum 1024 x 1024
VGA disconnected (normal left inverted right x axis y axis)
LVDS connected 1024x768+0+0 (normal left inverted right x axis y axis) 300mm x 220mm
   1024x768 60.0*+
   800x600 60.3
   640x480 59.9
TV disconnected (normal left inverted right x axis y axis)

Before changing xorg.conf to ignore TV, Xorg.0.log is filled with:

(EE) intel(0): Mode 1280x1024 does not fit virtual size 1024x1024 - internal error

This error message vanishes after applying changes to xorg.conf, mentioned in: https://wiki.ubuntu.com/X/Quirks#Ignore%20TV%20Output%20Quirk
Comment 1 Jesse Barnes 2008-09-22 13:21:45 UTC 
Hm, I was hoping the VBT parsing stuff I added would keep us from having to add more TV out quirks.  I'll apply the patch, but I'd also like to get a copy of the VBIOS from this machine.  Can you get it and add it to this bug?

Thanks,
Jesse
Comment 2 Bryce Harrington 2008-09-22 14:35:23 UTC 
Sure, I can ask the user; how do you retrieve the VBIOS?
Comment 3 Jesse Barnes 2008-09-22 15:02:57 UTC 
As root, do the following:

# cd /sys/devices/pci0000\:00/0000\:00\:02.0/
# echo 1 > rom
# cat rom > /tmp/rom.bin
# echo 0 > rom

then send me the resulting rom.bin.

Thanks.

Thanks for the vbios, yeah it looks like it's just wrong.  Maybe HP intended to ship a docking station with TV support but changed their minds?  Anyway Bryce's quirk should help.
