I didn't get any response for this. However, the workaround described in http://ubuntuforums.org/showthread.php?t=1584388 works for this card: boot in Windows, turn on bluetooth, turn off bluetooth/wifi in hardware with key combination fn-12, and boot in Linux. Maybe this could be a pointer if anyone is willing to look at the issue.
