I don't yet figure out why, but on my test the PAE install kernel crashed when 
Xen tries to start it on my debian xen host.

my config file - seems not too out of the ordinary, i uncompressed the kernel
after 1st crash, but that was just a random idea, no good.
kernel  = '/xen/kernels/netbsd-INSTALL_XEN3PAE_DOMU'
memory  = '64'
disk    = [ 'phy:vgxen/nb-test01-disk,sda1,w', 
'phy:vgxen/nb-test01-swap,sda2,w' ]
name    = 'nb-test01'
vif  = [ 'vifname=vif.nb-test01,bridge=xenbr0' ]

xend.log output was massive thats why i put it on 
http://www.pastebin.ca/873673 - as far as i can tell it was also useless.

the only uncommon thing about my system is the via c7 type cpu,
on this system i only use a PAE kernel because my bigger xen host needs it.

do you have any hint as to where i can look for a fix?
