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. It detects if the chip is rev 3.00 and aplies the patch only for it. 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.
