very bad, and very weird, scrolling text performance xorg 1.5.3 intel 2.5.1 GM965

[Thomas Jaeger]

You really need the glyph cache in the X server to get decent text
performance out of the 2.5 intel driver.  The patches are pretty
straightforward to backport, but it is my understanding that a 1.6
server will be uploaded to jaunty soon, so you might want to wait for that.
