Xen users - Mar 2011 - how should I go for Xen 4.0.1 with a non pv-ops Dom0 kernel

Hi,
I recently compiled a Xen-4.0.1 and pv-ops Dom0 2.6.32.27 kernel from
JF''s tree.Where my hypervisor could not boot and unfortunately the
system is rebooting so frequently that I am not able
to note down the error messages on a paper and pencil.So now I am
planning to go for a non pv-ops Dom0.I am not clear as what should be
the approach?
I have been Googling it every now and then and was not able to
understand this process exactly as how it is working.Does it need an
older version of Xen with 2.6.18 version kernel
or I can use a latest kernel also.

Does Xen-4.0.1 works with non pv-ops Dom0 kernel and if that the case
how will it work.Do I need to patch a vanilla kernel from kernel.org
with gentoo patches or some thing similar.
I am looking to compile every thing from scratch for my own
understanding.I have installed binary packages from Debian/CentOS and
used them.
But for a non pv-ops Dom0 kernel I am not clear with the procedure.Let
me know what should be the approach in this case.I want to do it on
Lucid 64 bit.
If some one can give me a relevant link to a tutorial that would be
great.It has been quite some time for me searching this problem but I
am not able to come to some concrete thing based upon my search.I will
be using Ubuntu 10.04 64 bit system.

In case the Xen-4.0.1 does not work then should I go with an older
version like Xen-3.0 some thing?

Your link is good I tried it but the results are not different.
menuentry ''Xen 4.0.1 with new kernel'' {
        root=''(hd0,1)''
        kernel (hd0,1)/boot/xen.gz noreboot
        module  (hd0,1)/boot/vmlinuz-2.6.32.27-pv-ops root=/dev/sda1
ro console=tty0
        module  (hd0,1)/boot/initrd.img-2.6.32.27-pv-ops
}


error: unknown command kernel
error :u need to load the multiboot kernel first
error :u need to load the multiboot kernel first
Press any key to continue

Now when I changed the entry to some thing like this

menuentry ''Ubuntu, with Xen and  Linux 2.6.32.27''  {
        recordfail
        insmod ext2
        set root=''(hd0,1)''
        multiboot (hd0,1)/boot/xen.gz dummy=dummy noreboot
        module  (hd0,1)/boot/vmlinuz-2.6.32.27 dummy=dummy nopat
root=/dev/sda1 ro console=tty0
        module  (hd0,1)/boot/initrd.img-2.6.32.27

}

Then even before I could note down any message on screen it becomes black.
