Flashing screen in X with Chips 65540

[Christian Rishøj <chrris@post1.tele.dk>]

Hi,

When running X in 15 bpp or more using the xfree86 server and the
specific model "chips 65540" on my Acernote 350 a lot of "trash" occurs
on the screen when moving the mouse pointer or when there is any
acticity on the screen.

This can be fixed by entering the text-mode hardware APM configuration
menu accessible through a button on the laptop and then returning to X
shortly after.

This is a bit annoying! Did any of you ever encounter similar problems?
