If you have a machine operating this way can you cut'n'paste a copy of that file so we can take a look.
Is there one file per CPU?
Could the files be different?

IBM has a good write-up here:
We're setting up a test on RHEL for next week. I'll let you know if anything interesting shows up.
The IBM docs are RH-centric. I believe SUSE uses the same /proc/ structure, but haven't confirmed that.
The standard governors require 2.6.12.
