They told me that my kernel was same as the /netbsd kernel. And they told 
me they made no changes.

I see that the default XENU config does have DEBUG and DIAGNOSTIC. I am 
just not sure why the module does not.

How can I find out if the pf.o is actually from the NetBSD/xen?

I can try to download a differnt pf.o to try. I haven't looked yet. But 
is there an download site that have individual files like that to 
download? Or what tarball can I extract it from for 3.0?

> [1] how come YOU are using pf? :)

You probably got me confused with the other Reed. Depending on the system, 
I use IPF, PF, IPFW, IP Tables...  By the way, I am still working on 
getting a PF book published -- it is almost ready :)
