I don't really care if you're using 8-CURRENT or 7-STABLE, the driver
source is nearly the same in both.  The problem exists in both, and the 
workaround is the same in both.  However, I was looking to collect
the PCI identification information for this 150-6 card so I could
hopefully teach the driver to automatically handle this card specially.
Thank you for providing the information.
