Yes, modprobe is silent on success.

There don't seem to be many Xen modules there. This may be OK if those
options are =y in your kernel configuration or it may be a problem if
they are =m.

Can you attach your kernel config please.
I've attached the kernel config file I used to build this kernel.
Also the output of
       find /lib/modules/$(uname -r) -name xen\*.ko
might be interesting.

Here is the output:

[root@XenTester su]#  find /lib/modules/$(uname -r) -name xen\*.ko
[root@XenTester su]#

Are all necessary modules included?

It should be fine. What exact changeset is it?

Could  you please let me know how can I find out what exact changeset it is? Sorry I'm not quite familiar with the Linux kernel structure.
