As far as being satisfied with it, I have to rely on yours and others input
since I don't have access to a FreeBSD machine.

Actually, that's confusing.  The copyright notice there is for "GKrellM" for which
I am overall the author except for several of the machine dependent files in the
sysdeps directory.  And for those files I should make the copyright notices
more clear since I am author of linux.c, but Anthony Mallet is author of
netbsd.c and Hajimu UMEMOTO is author of freebsd.c.  So I hope that
Hajimu will have the chance to review these changes.

For client/server mode debugging, run the client gkrellm with the
"-d 0x1000" flag and look for <cpu_setup> and <cpu> lines in the output.
It really should be working so long as you are running the gkrellmd
compiled with your freebsd.c changes.
