it's a very long time I'm wrestling with the very same issue with my mobility x1400.

I don't think it's the very same issue:

Option "EXAPixmaps"        "off"

This is a very big hammer which basically prevents 2D acceleration from occuring in most cases, so it doesn't narrow down your problem very much unfortunately.

Moreover, the original report here mentioned 'The effect does not show in screenshots', which means this option can't really work around it. So your problem is probably not exactly the same and should be tracked elsewhere.

Option "AccelDFS"        "off"
Option "MigrationHeuristic"    "greedy"

These options don't have any effect with KMS.
