        I'll handle this.  Yes.  Sorry, please wait:-).

        I have a patch which provides SB16 device on FreeBSD.
        On FreeBSD, sb16(sbc) driver finds it like following
        process.

        out(0x226, 3);
        (100 micro sec busy loop)
        out(0x226, 0);
        while(  in(0x22e) & 0x80  )  {
                (20 micro sec busy loop / MAX 1000 repeat)
        }
        if(  in(0x22a) == 0xaa  )  {
                FOUND!
        }  else  {
                NOT FOUND!
        }

        So I changed (val == 1) to (val & 1),  do you think so?
