Did you try "flags 0x20000" in the kernel config? It seems to be working on my system recently upgraded to 3.1. I haven't had a chance to test the serial port speed yet, because somebody walked off with my ISDN TA, but I'm supposed to get it back today. My two 16650 ports do at least probe correctly with the above flags. -- "Where am I, and what am I doing in this handbasket?"
