Comment 2 for bug 152445

after some search, it seems that it is the same as

https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.20/+bug/93331

or:

http://bugzilla.kernel.org/show_bug.cgi?id=8228

so please, patch dapper kernel with tables for Dothan processor - kernel.org seems to ignore the problem (problem is solved by bios upgrade). For my laptop there is no BIOS upgrade, and it does not have option in it to enable frequency scaling
