 Those are here:
 
 http://anduin.eldar.org/~brad/ctf/ctfdump_built_SAMWISE
 http://anduin.eldar.org/~brad/ctf/ctfdump_booted_SAMWISE
 
 Since this is a pure DOMU PV, the booted kernel lives on the DOM0 and
 the ctfdump was taken from there using the path indicated in the DOMU
 Xen config.  The two outputs appear to be identical.  I also placed the
 kernel in /netbsd on the DOMU, although there really should not be
 anything that cares much about that on a pure PV (and that didn't effect
 dtrace).

 Yes, I did that double check.  I am running the kernel build with "-g"
 as far as I can tell.  For completeness here is the "config -x" of the
 booted kernel:
