Upon mounting the ISO loopback I discovered there is no xen dir 
structure under install.amd (or anywhere for that matter) and that is 
why I removed it.  My hopes were that the lone kernel/initrd worked 
under Xen like the alpha 1 installer release page suggests.

No.

I am going to paste the xend log.  From what I see in that output is 
that it is ignoring all bootloader_args I specified and just passing 
"-q".  Maybe this explains why my manual pygrub test appears to work 
while this does not?  And yes I read the installer link you mentioned as 
that is where I got my base config from.
P.S.  Thanks for the response.
