Applying the BSP to the 2.4 kernel is a error prone process.  You need
to be using the *exact* version of the MontaVista kernel that EDK is
expecting, otherwise it breaks and you need to fix it up manually.
2.6 is much better and you don't need to copy over the whole BSP; just
the xparameters.h file.

I strongly recommend moving to 2.6.  I don't know if anyone has got
rtai going on it for the virtex, but your chances of getting help are
much higher because virtex 2.6 support is being actively developed.

As for the XUP board, I haven't had a chance to get mine running yet,
but I know others have had good success with it.

Cheers,
