It works , at least on iw 3.10.
If you have debug enabled you can see the value changing.
On a openwrt system
root@RSPro2:/lib/wifi# iw dev adhoc0 set txpower fixed 900
root@RSPro2:/lib/wifi# cat /sys/kernel/debug/ieee80211/phy0/netdev:adhoc0/txpower
9
root@RSPro2:/lib/wifi# iw dev adhoc0 set txpower fixed 1500
root@RSPro2:/lib/wifi# cat /sys/kernel/debug/ieee80211/phy0/netdev:adhoc0/txpower
15
And the received power changes on the station confirming that is making effect.

Just for posterity's sake, it seems you should really be looking
at user_power_level:
[root@ct523-9292 lanforge]# iw dev wlan0 set txpower fixed 1000
[root@ct523-9292 lanforge]# cat /debug/ieee80211/wiphy0/netdev\:wlan0/txpower
0
[root@ct523-9292 lanforge]#
[root@ct523-9292 lanforge]# cat /debug/ieee80211/wiphy0/netdev\:wlan0/user_power_level
10
Thanks,
