[Impact]
Laptops with 855 and earlier chipsets hang when the lid is closed.
[Addressed]
In Hardy we have been fixing these bugs on a case-by-case basis.
Upstream analyzed the situation and found all 855 and earlier chipsets need the Pipe-A quirk,
so they introduced a quirk upstream to solve it for all 855 and earlier cards.
We have been carrying this fix in Intrepid since Intrepid opened.
[Patch]
2-line change (attached below)
[Reproduction]
1. On any 855 or earlier laptop that has not already been patched,
2. Close lid
3. Hangs Xorg
See bug #138256 for a detailed discussion about the issue.
[Regression Potential]
In general we've found quirks to be highly stable and safe for backport.
This one is somewhat more aggressive than usual since it covers a large class of hardware.
The hardware it covers is quite old (and in fact no longer supported upstream anyway, really), so worst case is it may cause some regression in hardware we don't really support that well anyway.
However, due to the extensive analysis upstream and testing over the last 6 months, the chance of regressions are acceptably low.
This patch was first made available in July, around the time of Hardy's release. I've held off backporting it in order to accumulate a sufficient amount of testing. With Intrepid now released and no serious issues discovered due to this change so far, I feel comfortable backporting it for hardy.

For Intrepid, we're carrying the pipea quirk for all 855 and before chipsets, so this *should* be fixed for Intrepid. If not, please comment here, since that'd be highly unusual.
For Hardy, we can still backport the quirk fix.
