It's working now! I just compiled the kernel with Jeremy's stable branch
as of yesterday. I used the config-2.6.32-5-xen-amd64 from Debian and
built a kernel package the Debian way and voila! Everything else (but
the kernel) is a stock Debian Squeeze.

As a side note I'm using dom0_mem boot parameter and the BIOS firmware
is the latest for this Dell server.

I was hoping to get the patch merged in Debian's Xen kernel. Is there
anyone around here able to do that or should I just file a bug?
