Hmmmm, explain? I did a..

mkinitrd -v --with=ext3 /boot/initrd-2.6.18-xen.img 2.6.18-xen

and copied the /lib/modules/2.6.18-xen/ directories from Dom0 to  
DomU. This was all prior to getting the 'kernel tainted' message.
FWIW, cat /proc/sys/kernel/tainted in DomU gives a "2" which  
apparently means a module load was enforced in SUSE (couldn't find  
the relevant info for RHEL). "--with=ext3"?
