New details on my research...

* Xen Enterprise 3.1.0 installed on a 3rd clean server as dom0.
* Fedora Core 6 as domU booting with his *internal* kernel stored on tap:aio
file.
* FC6 domU 32bit (256 MB RAM) it just *wont* work if the machine has 4 GB of
RAM... but it's working if the machine has 2 GB RAM

Notes:
* Maybe kernel-xen-fc6 has problems with 4 GB of RAM?
* Current FC6-xen-kernels are 2.6.19... but a normal xen-kernel is 2.6.16
* Maybe an FC6 domU booting a standard xen-kernel will work on machines with
4 GB of RAM

His original email seemed focused on the hardware aspect of things so I 
was trying to provide information about a similar, working setup.  I did 
not mean to imply that is was exact as I use CentOS, not Fedora for my dom0.
