  Ok, I have proper kernel now. 8.2-STABLE about two hours long.

  Here is result:

gateway# ifconfig wlan0
wlan0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
...[<SKIPPED>]
        privacy MIXED deftxkey 2 AES-CCM 2:128-bit txpower 30 scanvalid 60
        protmode CTS wme burst dtimperiod 1 -dfs
gateway# ./athpoke 0x9934 0x9938 0x993c 0xa234 0xa238
0x9934 = 24242424
0x9938 = 1c1e2024
0x993c = 0000003f
0xa234 = 26262426
0xa238 = 26262626
gateway# ifconfig wlan0 txpower 15
gateway# ifconfig wlan0

0x9938 = 1c1e1e1e
0x993c = 0000003f
0xa234 = 1e1e1e1e
0xa238 = 1e1e1e1e
gateway# ifconfig wlan0 txpower 1
gateway# ./athpoke 0x9934 0x9938 0x993c 0xa234 0xa238
0x9934 = 02020202
0x9938 = 02020202
0x993c = 0000003f
0xa234 = 02020202
0xa238 = 02020202
gateway# ifconfig wlan0 txpower 30
gateway# ./athpoke 0x9934 0x9938 0x993c 0xa234 0xa238
0x9934 = 24242424
0x9938 = 1c1e2024
0x993c = 0000003f
0xa234 = 26262426
0xa238 = 26262626

  It seems, registers are Ok. But clients don't see any difference!
Maybe, it is because my Senao card is "powerful" one, with additional
schematic (and power supply) to boost signal?
