the tx power code in hostap assumes that 20dBm (100mW) is the maximum available. 23dBm (200mW) Prism 2/2.5 cards now exist from several vendors.

On one hand, this is merely cosmetic. 200mW interfaces are reported as 100mW interfaces:

wlan0     IEEE 802.11-DS  ESSID:"musenki"  
          Mode:Master  Frequency:2.412GHz  Access Point: 00:30:B4:01:0A:C4
          Tx-Power:20 dBm   Sensitivity=1/3  
          Retry min limit:8   RTS thr:off   Fragment thr:off
          Encryption key:off
          Power Management:off
          Link Quality:0  Signal level:0  Noise level:0
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:583680   Missed beacon:0

my concern is that there is no way to turn the power down on a 200mW card, and then to turn it back up.
