The answer is that you cannot (yet) set the output power in NetBSD.
It is possible to do it from software, however. Last I knew, the power
output adjustments on Linux were ad hoc and naive.

Will you describe what you are trying to achieve by adjusting output
power?  I only know my own applications for an output power adjustment;
I would like to account for others' applications in my designs.

(It is funny you should ask about this, because I have been holding a
private e-mail discussion on output power adjustments with M. Warner
Losh, and I began last night to lay the groundwork for this adjustment
in my private NetBSD sources.)
