Ubuntu Lucid: VMWare player hangs on notebook

VMWare player was constantly hanging after about 5 minutes of running on the Ubuntu host. I found this problem is related to CPU frequency scaling (Intel Speedstep on my Lenovo T60).
This is easily solved by installing the CPU frequency scaling applet on Ubuntu, then click on it and select a fixed CPU frequency while running VMWare. I recommend switching it back to on demand when you're done to save power.

An alternate workaround that makes these changes permanent and survive updates is here:
https://wiki.ubuntu.com/X/KernelModeSetting

basically run these commands:
# sudo bash
# echo options radeon modeset=0 > /etc/modprobe.d/radeon-kms.conf
# sudo update-initramfs -u
# reboot
