Done.

To recap here, my Debian Squeeze stubdom-based HVM domU is frequently 
not completely starting, freezing after the output "Writing SMBIOS 
tables ...".

I am emailing you offlist with a link to the trace now. I had to use 
"xm" instead of "xl" because "xl" still doesn't seem to work right with 
stubdoms (a separate bug); it probably needs to wait a little longer for 
the main domU to be created before creating the stubdom.
