Failed to initialize the GLX module in kernel 2.6.24-8-generic

I am running the alpha version of Hardy Heron. Yesterday, my kernel was updated to use 2.6.24-8-generic via update manager. Since then compiz has stopped working. Upon examining the Xorg.log file, I see these errors that weren't present earlier:

-----------
dlopen: /usr/lib/xorg/modules//libglx.so: cannot open shared object file: No such file or directory
(EE) Failed to load /usr/lib/xorg/modules//libglx.so
(II) UnloadModule: "glx"
(EE) Failed to load module "glx" (loader failed, 7)
....
(EE) NVIDIA(0): Failed to initialize the GLX module; please check in your X
(EE) NVIDIA(0): log file that the GLX module has been loaded in your X
(EE) NVIDIA(0): server, and that the module is the NVIDIA GLX module. If
(EE) NVIDIA(0): you continue to encounter problems, Please try
(EE) NVIDIA(0): reinstalling the NVIDIA driver.

How do I go about it?
