xen 2.0.6: which NetBSD-kernel and where to find?

[Rainer Brinkmöller <rainer.brinkmoeller%web.de@localhost>]

i received a mail from xen-user/devel-list (Ian Pratt):

The Xen team are pleased to announce the release of Xen 2.0.6 !
This release includes support for Linux versions 2.6.11.10 and 2.4.30,
NetBSD 2.0 and FreeBSD 5.3, along with many bug fixes.

So i tried to setup a environment like the following:

domain0:
NetBSD 2.0.2
xen-2.0.6.gz
pkgsrc.tar.gz from may 21.

First i setup NetBSD 2.0.2 as usual. Later xentools20 (which, i read, 
was updated by Juan RP)
Then wondering about the xentools20 make install because first it did 
download was xen-2.0.3-src.tgz.
2.0.3 ?
Why not 2.0.6 ?
When executing the command "cd /dev && sh MAKEDEV xen" there is still 
the message: "MAKEDEV: xen: unknown device".
Sure. MAKEDEV isn't updated now for NetBSD 2.0.2 cause i used my old 
iso-image ;)
Is the new NetBSD 2.0 and/or 2.0.2 iso image on the ftp-server updatet 
for this?

I also wondering that i could not found any XEN0 or XENU kernel for 
current or 3.0_BETA on the ftp-server.
Also i am missing the ftp-URL 
ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-daily/netbsd-3/200505060000Z/i386/
where i did download the first working NetBSD 3.0_BETA XEN0, XENU and 
INSTALL kernel.

What NetBSD kernel are recommended to use now?
Where to find actual NetBSD/xen-kernel?

Greetings, Rainer
