64-bit 8756 drivers w/ 6150, Xorg 7 but no desktop OpenGL apps?

Have any of you guys w/ 6150 boards gotten desktop OpenGL apps to work w/ Xorg 7 and the latest 8756 drivers? I'm running a resolution of 1280x1024x24 according to xpyinfo:
screen #0:
dimensions: 1280x1024 pixels (392x292 millimeters)
resolution: 83x89 dots per inch
depths (7): 24, 1, 4, 8, 15, 16, 32
root window id: 0x64
depth of root window: 24 planes

but when I try running foobillard, I get this error:
Video mode set failed: Couldn't find matching GLX visual

and when I try running amoeba, it only shows me a color depth available of 1 and running it causes X to restart

Both of these apps were installed via apt-get and 64-bit versions were run.

glxgears complains as well:
Error: couldn't get an RGB, Double-buffered visual

Tremulous (a Q3A engine game) runs fine, but it runs fullscreen and is a 32-bit app.

In the BIOS, I gave the 6150 64MB of shared memory for video memory.

update: reinstalled the nvidia drivers and now all is well. I thought we only had to reinstall the drivers when installing new kernels...I've only done dist-upgrades...

Installing a new version of X can overwrite libglx.so with the Mesa version. Reinstalling the drivers will restore the NVIDIA libglx.so. glxinfo will tell you which server glx implementation is being used, as will Xorg.0.log.

Thanks, Aaron. That explains it. There have been a lot of Xorg 7.0 changes lately and I've been dist-upgrading to try to keep up :-)
