This is strange, I'm using the same scripts and almost the same 
configuration as you. While my sleep used to fail to resume for a 
mysterious reason once in a hundred times or so, for the past few months 
both sleep and hibernate have been rock solid and failed only 
deterministically, for good software reasons. The big difference is that 
mine is a T40.

Sorry to hear about your frustration - I know the feeling, it took me 
forever to figure out the insanity that is laptop support on Linux (and 
still no display hotplug!) - but I'm stumped. The only thing that comes 
to mind is toggling the EnableVbetool option and related options in 
/etc/hibernate/common.conf - but if it's having trouble resetting the 
video, that should manifest itself on startup, not shutdown...

Might also try other kernel versions. Like a really old one - sleep has 
been reliable for me since at least 2.6.17.

Finally, try Feisty (now in beta). It has all the latest and greatest 
voodoo for laptop hardware support. (You could also install the relevant 
package port that I'm maintaining for Gentoo,
