xorg-x11 locks up on centrino when using 3d acceleration

[wiremore]

Hey,

First I want to say that gentoo is awsome. I switched from fedora core a month ago or so, and i havent looked back. It is a bit more of a pain to get everything working though.

I have a brand new asus m5n centrino laptop. It uses the 855gm graphics chipset. Im trying to get hardware graphics acceleration to work. I have the 2.6.10-gentoo-r6 kernel. I have agpgart and intel-agp built as modules, and drm support.

When I try to start x after loading the i830 module, I get a black screen with a little x shaped cursor thing, and then this little white box shows up near the middle of the screen. It changes shape a little if i press a lot of keys. ctr-alt-backspace and ctr-alt-delete dont work. If i press the power button, the box gets a little more filled out (normally its kind of a bunch of lines in a box shape) and in a few seconds the computer shuts down.

Loading X works just fine without the i830 module, but dri support is not enabled


EDIT: xorg logs

You probably needs to enable
this option in your kernel configuration:
