Description of problem:
I have an embedded "mini-PC" style machine with a Transmeta Crusoe
CPU, which is configured to always operate at its highest frequency. 
The 2.6.5-1.327 kernel crashes due to a division by zero in the
cpufreq/longrun driver.

The attached patch fixes this problem.  It has also been sent upstream.


Version-Release number of selected component (if applicable):
kernel-2.6.5-1.327

How reproducible:
Always

Steps to Reproduce:
1. Try to install FC2t3 on a machine with a degenerate Longrun
configuration.

    

Actual Results:  Kernel panic on boot.

Additional info:

Patch attached.
