The xdm problem was a minor distraction caused by the switch to modular  
X.org; now I have joy there.  I found the "noreboot" Xen kernel  
configuration option and managed to see what I think the problem is with  
running Xen 3.3.

(XEN) *** LOADING DOMAIN 0 ***
(XEN)  Xen  kernel: 32-bit, PAE, lsb
(XEN)  Dom0 kernel: 32-bit, lsb, paddr 0xc0100000 -> 0xc0a51c54
(XEN)  Dom0 symbol map 0xc0a51c54 -> 0xc0b1e4c0
(XEN) Mismatch between Xen and DOM0

I assume the mismatch is the PAE thingy.  In looking at the xenkernel33  
package for about 10 minutes, I didn't see any way to tell it to not build  
with PAE support.  (My PC doesn't have enough memory in it to need PAE,  
anyway.)  Why doesn't the kernel produced from the package work with the  
prebuilt NetBSD kernel?  What am I doing wrong?
