It takes about 40 sec's here .. the time is required to copy all the 
information on open programs onto a file in your swap.

It takes about the same time as a reboot.  When it comes up the 
(k)ubuntu splash screen progress bar freezes and disk activity is 
constant because it's reading and starting all the app's from the file 
in swap.

I don't think it's faster, but yes, it works "most" of the time here.  I 
can't get repeated hibernations with compiz, so compiz is off for now 
(Menu => Appearance => Desktop Effects => none).

It also depends on which video card you have and which driver.
