Ok, "iw phy phy0 set txpower fixed|limit 2000" does work, I fell
into the 'must be multiple of 100 but I won't give you any helpful
error message to tell you this' trap.
I also now believe the value for max_power below should be
AR5K_TUNE_MAX_TXPOWER/2 (31dBm) (or even better use calibration
data from the eeprom).
Still need to figure out why it boots up with txpower set to 0
though...
