How can I tell which bits I'm currently testing?
I did the "svn up" about 2h ago.

svn is now telling me:
grundler at iowa:/usr/src/linux-ia64-release-2.6.10/drivers/infiniband$ svn up
At revision 1311.
grundler at iowa:/usr/src/linux-ia64-release-2.6.10/drivers/infiniband$

Before we were using the original HP firmware that exposes
the virtual bridge but hides the "3rd BAR".

I will eventually go back and try with such a card again.
But I think being able to use a reflashed card would be just
as important for openib.org than using the original HP card.
