Yes, it is possible.  I have a Virtex-II Pro with Linux running on it
although I didn't configure it myself (it is one of those Black Dog
computers).  I work with Virtex-4s right now.

Can you try a reference design for the Virtex-II perhaps?

Can you comment out memset_io and write your own version of it (which
you can insert debug statements into)?

When/where in memset are things breaking?  What is the nature of the
breaking?  Can you get your serial terminal to print out hex values
(for memory locations, memory values, etc.)?
