Interesting.  'xl debug-keys h' got me ~1448 bytes onto the serial 
console, except it is old buffered output from exactly where it left off 
during boot. 1448 bytes is about the size of 'h' output from another 
working box.  The same thing happened with 'm'.  Xen is flushing an 
equal amount of characters from the buffer as generated by debug-key 
command output.
I can continue to poke the buffer until I see output from things I've 
issued, however it still refuses to respond to serial input 
(control-aaa) nor can I get dom0 to echo chars.  It's currently running 
a * dump which has been going now for over an hour, currently on vcpu 
435628.  I won't be doing that again.
Any lightblubs going off?
