There's some bad karma for this system and Ubuntu with this release.

After the installation of the bundle and launching Vmware Player, the modules building fail for vmnet and some other components. I've seen a patch for a previous version of the player on RT Kernels, but I'm yet to find a fix for this one.

This is an Ubuntu Studio 9.10 i386 with the released 2.6.31-9-rt kernel running on an Asus A8Js.

Here's some output from the console when launching vmplayer, I'm attaching also the log and the complete output for further analysis:
