Congratulations.  If you had to make any changes to get it to work
then please send me your patches.

You'll have to go back into the mailing list archives to find a patch
for adding PCI support for a Virtex platform.  I don't have any of
that in my tree.  It probably only exists for the 2.4 kernel.  You'll
need to port forward to use it on 2.6 (I'm more than willing to help
you with this)

However, word of warning.  The Xilinx PCI bridge is badly broken.
Xilinx is not supporting the PCI core and it is missing the ability to
do certain types of transfers.  Last I heard, Xilinx has no plans to
fix their PCI core either.

Best of luck,
