Interesting:

XENBUS: Device with no driver: device/vbd/2048
XENBUS: Device with no driver: device/vif/0
Freeing unused kernel memory: 124k freed
device-mapper: 4.5.5-ioctl (2006-12-01) initialised: dm-devel@redhat.com
Kernel panic - not syncing: Attempted to kill init!

Not sure where to go from here.

Hm, everything below, at a first glance, seems to be right.  What does the
console output look like from the RHEL-4 kernel (make sure to take rhgb quiet
