Activating Afterburner (125Mbps) on the recent wl-500g units

[cu112]

It works on a very old Belkin F5D7230-4 (hw 1222df) ! (with Oleg's 1.9.2.7-6c-pre5 firmware)

wl gmode:

gmode   Set the 54g Mode (LegacyB|Auto||GOnly|BDeferred|Performance|LRS)

nvram show | grep afterburner:

wl0_afterburner=auto
wl_afterburner=auto

I left gmode in 54g Auto (1) and voila, when i connect with my Belkin F5D7011 High Speed Mode pcmcia adapter, linkspeed is @ 125 mbps ! Effective throughput at short distance is 25 mbps, with peaks above 30 mbps, quite a bit better than 54g performance (which maxed out at 20 mbps)

Anyone got any ideas why i can't see the Afterburner option when i execute "wl gmode help" ? (i've tried the srom register at 39 with value 0x020f but that didn't make any difference)
