Intel 4500HD issues (No opengl, no video overlay)


I have a notebook with the new Intel GMA 4500HD which of course is supported by the xorg intel driver. I'm running the latest version (2.5.1-r1 from Gentoo/portage) but I'm having some issues with it. I feel they are somehow connected.
First of of all I have no working GLX (or rather opengl or what ever - i cant tell the difference)
Strange thing is that glxinfo | grep direct returns: direct rendering: Yes
And glxgears runs exactly once and reports 1316 frames in 5.0 seconds = 262.839 FPS. When i run this a second and a third time glxgears aboards with Error: couldn't get an RGB, Double-buffered visual
Setting a opengl game like supertux :-) to use opengl causes the game to crash.
(glxinfo still reports the same - so the driver seems not to be crashed or something)

AIGLX didn't worked as well (xorg log reported something like dlysm (or something) then __*something*2005*numbers* didnt worked (I cant remember if needed i will reproduce the error and post the exact output)) however i just turned AIGLX off because that this compiz/berly thing i dont need right now - but would be nice to have this working somewhere in the future. anyway.

But the biggest issue right now is that xvideo doesnt support Video Overlay. Only textured video is available which causes the videos to flicker (I googled it. the problem is called tearing)
xvinfo | grep Adaptor only reports Adaptor #0: "Intel(R) Textured Video" where it should report Adaptor #1: "Intel(R) Video Overlay" as well.

Since they all three problems have something to do with opengl/dri/glx stuff i guess there is one solution for all of them. So please help me fix it. I really need this going. esp the xvideo stuff.

cheers Daniel

I've just noticed that I'm using the DRM_I915 driver in my 2.6.28 kernel without patches (just the few gentoo patches)
cat /usr/src/linux/.config | grep -i drm returns CONFIG_DRM_I915=y

Other drivers are not enabled. Now i'm wondering if this is the right driver. Is there a drm_intel one?

please help!

cheers Daniel

edit: I give you the dmesg output as well since all drm stuff is not compiled as a modules
