thanks a lot for the detailed info,
i will stick with my compiled version for a while, and see what the future brings.
if really needed, i'll go for RH/CentOS - but first look around for a debian-based solution.

Official Xen supports only 2.6.18 based kernels.. I don't know why you
want to avoid RHEL or CentOS, but at the moment they're one of the best options
to run as dom0 (they've done a lot of testing, patching and certification on
different server hardware). RHEL/CentOS 5.x is 2.6.18 based with a lot of
the new drivers backported.

Ubuntu 8.04 LTS has 2.6.24 based dom0/domU kernel, but it's a forward-port of
2.6.18 stuff, and based on people's comments it's not very stable.. basicly
all of the later 2.6.2x dom0 kernels haven't been as stable as 2.6.18 based

It's a lot of work and a huge mess to forward-port these 2.6.18 xen features
to a new kernel every time new kernel gets released.. that's why noone wants
to do it. And that's why Redhat/Fedora started working to get the xen stuff
integrated into vanilla/mainline kernel.org kernels.. ie. using pv_ops. That
way (in the future) you can use the normal kernel for xen vm's too.. without
any extra patching or forward-porting.

This is the status page of pv_ops domU kernel-xen for 2.6.25:

Progress/status page about xen dom0 pv_ops work is here:

Some of the xen pv_ops features are already in 2.6.24/2.6.25 kernels, and the rest
have been sent for upstream inclusion, or will be sent shortly, I think.

This means that in the future we should be able to run the normal/vanilla kernel
also for xen virtual machines (and for dom0).. but unfortunately not yet

Recently released Fedora 9 has this 2.6.25 based domU kernel-xen, for both i386
and x86-64.
