Ah, thanx.  That's what I suspected, after sending my mail, I grepped
around in the source of hostap-driver, for ENOTSUPP in hostap-ioctl.c
and found

        case PRISM2_PARAM_WPA:
                local->wpa = value;
                if (local->sta_fw_ver < PRISM2_FW_VER(1,7,0))
                        ret = -EOPNOTSUPP;

and some more grepping showed that STA seems to be the fw version.

So, my next question is:  Is there a way to update the firmware under
linux?  The system is an embedded PC104 board and I'd rather not
disassemble it completely to pull the Prism2 card and insert it into
some Windows box.
