grub 2 and booting xen dom0

[Matthew <Matthew@centrum.sk>]

    Hi,

I'm trying to boot a xen-3.1.gz with grub2, but without any luck. The
only message I get is:

	Error: Invalid magic number

after specifying
	linux /boot/xen-3.0.gz dom0_mem=262144


Another question:
	What should I use instead of the module command (from grub legacy).
The xen docs instruct to use:

title Xen 3.0 / XenLinux 2.6
	kernel /boot/xen-3.0.gz dom0_mem=262144
	module /boot/vmlinuz-2.6-xen0 root=/dev/sda4 ro console=tty0
	module /boot/my_initrd.gz


for specifying the xenLinux kernel and initrd. For kernel we have the
linux command in grub2, but what (or how) to use insted of the module
(of course, with the former meaning as in grub legacy).
