Does the keyboard respond? Compile your kernel with CONFIG_MAGIC_SYSRQ, and when the freeze happens, press some of the sysrq keys like: alt+sysrq+t alt+sysrq+b Does the system respond in any way? Also, please test with the lastest development kernel which is vanilla-sources-2.6.26_rc1 as of this writing.
Please fell free to reopen once you've had a chance to try the steps in comment #1.
