fedora 7 xen doesn't want to start

Hello, I just installed on my Asus L3400Tp fedora 7 (5 GB partition for /,
34 GB for /home), and included vairtualisation with xen in the install.
My laptop only supports para-virtualisation, but that doesn't bother me.
After that, I did yum update, so now I´m with the kernels as shown in the
following exerpt of grub.conf:

title Fedora (2.6.22.1-41.fc7)
root (hd0,0)
kernel /boot/vmlinuz-2.6.22.1-41.fc7 ro root=LABEL=/ rhgb quiet initrd
/boot/initrd-2.6.22.1-41.fc7.img
title Fedora (2.6.20-2925.13.fc7xen)
root (hd0,0)
kernel /boot/xen.gz-2.6.20-2925.13.fc7 module
/boot/vmlinuz-2.6.20-2925.13.fc7xen ro root=/LABEL=/ rhgb quiet module
/boot/initrd-2.6.20-2925.13.fc7xen.img

However, when I try to start xen, de following messages appear:
mount: could not find file system '/dev/root'
setuproot: moving /dev failed: No such file or directory
setuproot: error mounting /procs: No such file or directory
setuproot: error mounting /sys: No such file or directory
switchroot: mount failed: No such file or directory
Kernel panic - Not syncing: Attempted to kill init!

And a reboot follows.
Ik start suspecting a bit that the 'module' vmlinuz-2.6.20-2925.13.fc7xen
for xen has a different approach of the hardware, that kernel
xen.gz-2.6.20-2925.13.fc7 does something strange with it.
Something else to note, is that Fedora 7 approaches the harddisk as a
serial device (/dev/sda) although it really is a parallel one. Previous
Fedoras always approached it as /dev/hda, could that have something to do
with it?

Cheers,
ario
