No resume on Sony GRX690

[Ed Gould <ed%left.wing.org@localhost>]

I'm running -current (4.99.72, today's sources) on a Sony Vaio 
PCG-GRX690.  Suspend (via sysctl -w machdep.sleep_state=3) appears to 
(mostly?) work, but the machine wil not resume.

By mostly works, I mean that the machine appears to shut off (e.g., the 
fan stops and the "on" light blinks yellow), but the screen does not go 
off.  It does appear to dim some, though.

Any thoughts on debugging this?  Any useful information to provide?

Thanks.
