Subject:    [PATCH] Add CPU speed detection to KPersonalizer for FBSD
From:       Adriaan de Groot <adridg () cs ! kun ! nl>

[Download RAW message or body]

Attached patch is a first stab at adding CPU-speed detection to
KPersonalizer for FBSD. For the vast majority of FBSD systems out there
the speed will still be detected as 0 [which makes me wonder, why is the
CPU speed detected at all, and what is KPersonalizer doing with it?], but
in some cases (-CURRENT, ACPI enabled) the right speed is returned.

The patch also corrects an indentation mistake and adds a comment that the
CPU speed is expressed in MHz.

OK to commit? Please CC me on replies.
