Bug#639931: [grub2] "update-grub" adds line to "multiboot" with Xen kernel

[Ben Holt]

I ran into this bug and couldn't find any reference to 
GRUB_CMDLINE_LINUX_XEN_REPLACE in /etc/grub.d/20_linux_xen until I 
looked at the sid package.  The bug where this was actually fixed is 
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=617538.

It sure would be great to get this backported to squeeze, I'd like to 
think others would otherwise waste as much time trying to sort this out 
as I did.
