No.  I don't expect any changes with the new card.  It is the same
chipset, and the layout is better.  We are also eliminating a connector
in the antenna path (won't happen till C1.)

It is hard to tell the difference w. 512 MB.  There is a maximum of 12%
slow down in tests that we've run.   Still, we consider the XO-1.5 to be
a 1GB machine and view this as a rare variance.
