I've just recently been looking into this too. I used the mentioned
patch and also linux driver source and have come with the attached
patch. It contains one more change but I don't know if it's correct. It
works for both chips on CURRENT for serial console.
The author of the patch mentions it isn't binary safe - sometimes the
chip stops working. I planned to test it with binary transfers (ppp)
today, check if it's working and submit it (with some cleanup) for
inclusion in FreeBSD.
