As I am interested in looking at Xen for the first time and I have a
debian sarge machine, I followed the first part of your howto.
Unfortunately on reboot I get the following:

and then nothing at all, boot does not continue.

Using versions of kernel and all xen packages from your howto.  Once
I get someone to go and reboot the machine I can get you the kernel
.config for dom0.

Any ideas what is wrong?  Should I just disable everything to do
with AGP in the meantime?

Also, I noticed this further up:

WARNING: Failed to register Xen virtual console driver as 'ttyS0'

I have a terminal server attached so normally my kernel lines in
grub would look like this:

kernel /vmlinuz-2.6.10 ro root=LABEL=/ console=tty0 console=ttyS0

so I added a console=ttyS0 on the end of the kernel line from your
howto.  Was that wrong?
