Details:

When using the module command, for example when booting a Xen kernel, the
first argument is not being passed to the kernel.

For example, the following configuration does not work:

menuentry "Xen 3.4 / 2.6.31.12 Xenified" {
insmod ext2
set root=(hd0,5)
multiboot(hd0,5)/boot/xen-3.4.gz 
module (hd0,5)/boot/vmlinuz-2.6.31.12 root=/dev/cciss/c0d0p5
module (hd0,5)/boot/initrd-2.6.31.12.img

The root argument does get passed to the kernel, resulting in the system not
booting. If a dummy argument is added before the root argument, everything
works OK:

menuentry "Xen 3.4 / 2.6.31.12 Xenified" {
insmod ext2
set root=(hd0,5)
multiboot(hd0,5)/boot/xen-3.4.gz 
module (hd0,5)/boot/vmlinuz-2.6.31.12 dummy=dummy root=/dev/cciss/c0d0p5
module (hd0,5)/boot/initrd-2.6.31.12.img
