OK, the code is modular enough to separate the dependant code into
different places.

Yes, that's my problem. In Linux I can get from /proc/cpuinfo for
example: name, model, stepping, cache size, clock speed, supported
extensions, etc...
But using sysctl in FreeBSD (sysctl -a) I can only see name and vendor
for the cpu and a few more things. Am I limited to the variables
showed in sysctl -a?

Thanks in advance.

BTW if this is isn't the proper list to continue with this thread, let me know.

Cheers.
