I managed to startle some of the other passengers on the flight back from
Usenix with a muffled "Shit!  Of course." half way through.

As well as upgrading, I built a kernel with the USB drivers in at the same
time.  That's when I started seeing the problem.  I tried building another 
kernel without them, but suspends still froze the machine.

What I did *in addition* to adding the USB drivers was follow their 
suggestion in the boot probes to enable the "Plug and Play OS" option in 
the BIOS.

If I turn this option back *off* then suspend/resume works fine again, with
or without the USB drivers compiled in.

Still don't know why PnP has that effect though.
