the answer is yes - there hasnt been an update to the driver. Andre Hedrick says he has fixed it a month or so ago but has not released it yet.
btw echo "max_kb_per_request:15" > /proc/.ide/hdX/settings is not for good performance (it may halve your performance on some drives) it is a bug workaround.
Look forward to testing libata on Silicon Image.
