Okey Dokey Bob.. :)

The current spec uses the soft cores and whichever of the canned uarts
that is entirely hardcoded, the name escapes me for the moment.  We
really do need the interrupt controller though, I've found a bunch of
appnotes which help- hopefully the driver suite will cover most of this.

I should have a good sense of the compatibilities between the drivers
and our board in the next day or so.  As I work through it, I'm going to
keep in mind the desirablility of runtime discovery where possible so we
might be able to set up a somewhat "generic" Virtex4 PPC bsp, sort of
like the motorola_shared familiy.  I'll keep in touch.
