3) Hibernate actually takes much longer than 30 seconds on your hardware.

Either 30 seconds is a lot longer than I realise, or hibernate on my
hardware takes about 2 minutes.  I had to raise my hibernate threshold
in Kubuntu to give it enough time because it'd blinker out partway
through.  And then resuming also takes like 2-3 minutes.  Given a 12
second boot time, logging in and restarting all the apps takes less
time than resuming.  Anything that can be done to make hibernate
happen faster than booting a Pentium II...would be very welcome.

(I'd also like to laugh at what was said earlier in the thread about
the rate at which battery is used during suspend to RAM.  My specific
hardware does now last more than a full night in suspend, as of about
Lucid, but I'm sure there is more out there that can only stay
suspended for 8-12 hours from full to depleted.)
