Support for Longhaul ver. 2 broke driver for VIA C3 Eden
600MHz with Samuel 2 core. Processor is not able to switch
frequency anymore. I don't know much about this issue at
the moment, but until (if ever) I will know why, this part
should be reversed. I hope it isn't to late to include it in
2.6.21.

gah, this went to linus yesterday, hopefully he hasn't applied it yet.

Please ignore. It isn't fixing anything. I don't
know at the moment if ver. 2 support is to blame,
or frequency test is doing it's job and it is
returning correct CPU frequency.
