Ok.

So you have a initrd problem like many many Xen users, the sad story is 
that there is no easy solution, a bunch of people are working and trying 
to get it to work, BUT it is intimatly related to linux complex boot 
process using ramdrives. My only successes so far were with compiling my 
own kernel, then you face the problem of wjich options to turn on/off 
and there again, it is a trial and error approach at best which requires 
tremendous time to do.
I made one working under CentOs BUT I now have iptables not working and 
have NOT yet figure out how to enable it even mu kernels are compile 
with it. As for people who claim to simply install the REL4 RPMS, well I 
did it at first BUT they simply don't boot at all, maybe these folks 
could post a detailed howto for the exact requirement of the ramdisk for it.
Keep us all posted, I am doing around 4-5 compile everyday.
