The drivers OUGHT to be dynamically determining the power required.

Oh and the limits (for the 2.4GHz band) depend on where you are:

US: 1000mW EIRP
Japan: 10mW/MHz EIRP
most of elsewhere: 100mW  EIRP

Note that these are radio signal strengths not power consumption values.
They depend on the aerial used.
