Thanks Arthur for the hint.  I will see if I can solve the problem and will report back.  It seems to be a problem with many users as it can be seen from Ubuntu forums.

I tried the free nVidia driver but it caused more problems.  The system would not wake up properly (just a blank screen) and the quality is very low.  The quality is fine on a normal display but on a wide laptop panel it does not look good.  The blank screen I think does have workarounds, though.

I actually installed Kubuntu 9.10 to give the new KDE a try.  It was then that I realized the new kernel in Kubuntu does a better job so I reinstalled Lenny (I always return to Debian) with the newer kernel.  In Kubuntu it worked very well out of box so this mush be software issue.

I also tried a recent version of Ubuntu 9.04 and 9.1. But they have done strange things to their suspend/resume packages. For instance, it's not longer possible to use the s2ram tool to trouble shoot suspend and figure out the right parameters to pass during suspend. That's fine when it works out of the box, as it did for you and most people I would expect, but when troubles arise it is very difficult to find solutions. I think policy kit is somehow handling suspend on ubuntu now IIRC.
Check out this link for good info how how to use s2ram for finding the right parameters. http://en.opensuse.org/Pm-utils
Once you find some that work you'll just have to debianize the instructions by reading the relevant pm-utils man pages for debian.
Good luck,
