Looks like there's been over 5000 errors like this:
 "Oct  1 09:32:24 192.168.0.61 kernel: [152372.345437] end_request: I/O 
error, dev nbd0, sector 200314"
 since yesterday morning.

GDM hanging definitely stops the thin clients from booting up. This is a 
little harder for me to debug because I don't yet quite get exactly how 
the new event based launcher works.
What happened monday was that apparently X stopped liking (maybe there 
was an update) my server's ATI ES 1000. I finally was able to switch to 
framebuffer and that got passed "Starting Gnome display manager", which 
then allowed some other service to start which allowed the thin clients 
to boot.
