Hi,

I solved the problem myself.

In the boot menu /boot/grub.menu.lst I added a parameter max_loop=64
to the vmlinuz module line:

module /vmlinuz-2.6.23.1-900.ccj58-xen
root=/dev/disk/by-id/scsi-SATA_ST3250820AS_5QE2G6DL-part5
resume=/dev/sda10 splash=silent showopts max_loop=64

And also copied all the kernel modules to the domU to avoid messages
about no modules found etc...:

Mount the disk image

mount -o loop /data/xen/domains/disk.img /mnt/tmp

Copy all the modules to the domU

cp -rp /lib/modules/* /mnt/tmp/lib/modules

(In the domU configuration the kernel used is the dom0 kernel : kernel
 = '/boot/vmlinuz-xen' )

Unmount the image umount /mnt/tmp and do this for all your images you use

As I did all these things, I could reboot with all the domU domains
coming up and all the networking necessary! Even the console works: xm
console domU-name gices me access

Hope someone can use this information.
