The only noticeable change between 2.11.4.1 and 2.11.5 that could
affect this is Otavio's addition of mode validation. There wasn't any
other significant change in the LX driver component.

I'll also mention that this change has been reported to break OLPC
DCON support because the XO-1's particular panel size suddenly got
invalidated. https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-geode/+bug/433228

Personally, I'm extremely tempted to revert
3af472f4453f8e92a9f303e64e2796836374d980 for now.  Otavio, any
comments?
