ah ok. A question: Why the the error-message that cryptic :) ? 
Isn't it (easily) possible to give out the involved line, or a short
description why it failed or at least replacing "segment" with "device"?
(The latter is another question, why is it a "segment"?)

Yes I do. See below, tho

Well, I have another config, this time it is just a "test"-case, it uses:
disk = ['phy:/dev/wd0a,0x3301,w' ]

(The NetBSD-guide noted that xen wants to look-up the second argument, 
and make something so linux likes it better or whatever; However the guide
says that xen would try to lookup hde1 on netbsd (that is not there); 
Said guide is http://www.NetBSD.org/Ports/xen/howto.html . Scroll down to
"Create Linux unprivileged domains". (Actually, is major << 8 + minor of 
hde1 0x3301 :D ?))

However, that also gives me that error, so "uname=phy:/dev/wd0a". And trust
me, that is there ;)

Well I deleted the sed-part that made /dev/ disappear. This time I 
get the old error, device (vbd (uname file:/xen/...) (dev hda1) (mode w)), 
error 8
