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.
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.
If both internal and external monitors are active, this problem does not exist.
Occasionally the flickering will stop.

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.

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: 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 monitor will start flickering.
If both internal and external monitors are active, this problem does not exist.
Occasionally the flickering will stop.
