Your single anecdote is not more convincing to me than documentation
provided by Toshiba themselves, especially when there is no drawback to
doing it this way.  I didn't know there were problems until I upgraded
to 2.6 from 2.4+pcmcia-cs, and I suspect many users have not done so
yet.  Also, using PCI_DEVICE_ID_TOSHIBA_TOPIC95_B would be more
specific.  I'm not sure why PCI_DEVICE_ID_TOSHIBA_TOPIC95 is a synonym
for it.

Ok, I'll do this.
