** Description changed:
SRU Justification:
- Impact: On laptops with pineview graphics external monitor only mode can
cause the output to flicker.
- Fix:
- Upstream commits:
- 9553426372eef71c849499fb1d232f4b0577c0f9
- d4294342fd4b94a3297867da00c1c5e929c28d4f
- These fix the issue by adding in proper support to set the Pineview
CxSR registers. On patch ensure the hooks are setup properly and this state
isn't overwritten, and the other patch adds a table which contains proper
memory latencies for DDR3 memory on Pineview.

- Testcase:
- 1) Connect external VGA monitor to laptop.
- 2) Set mode to external VGA only with its maximum resolution. (see test.sh)
- 3) Use xrandr to rotate monitor a few times, and turn on and off (see
irritate.sh)
- 4) Press a few keys on the keyboard, and the keyboard will start flickering.
+ Testcase: see below.

This bug is present in lucid (2.6.32-41 #90), but is fixed in maverick.
If I install the maverick backported kernel it fixes the issue.
More specifically its fixed in v2.6.35-rc2
(79a78dd6266a4f3e31c800e941ec62e250770a7d)
And broken in v2.6.35-rc1 (6c9468e9eb1252eaefd94ce7f06e1be9b0b641b1)
However, bisection between these commits has not been successful in isolating
the patch.
To reproduce:
1) Connect external VGA monitor to laptop.
2) Set mode to external VGA only with its maximum resolution. (see test.sh)
3) Use xrandr to rotate monitor a few times, and turn on and off (see
irritate.sh)
- 4) Press a few keys on the keyboard, and the keyboard will start flickering.
+ 4) Press a few keys on the keyboard, and the monitor will start flickering.
If both internal and external monitors are active, this problem does not
exist.
Occasionally the flickering will stop.
