Well ... in theory.

In practice, for instance, my laptop had suspend/resume working shortly
after I got it, and the widescreen video too.  Most of the problems were
video related, so I did interact with the upstream intel video driver
people, but by and large it was a set of black magic rules to restore
the video to its prior state (in my case, even the vbe tools didn't work
and I had to manually save and restore the pci config space).

The point, though, is I'd be incredibly surprised if a kernel hacker had
an unfixed suspend resume problem (except possibly one that just
appeared in the latest upgrade).  It's a fairly important feature and
hackers tend to get annoyed by problems like this and hack on them until
they're fixed.

However, persuading us all to go to the fix my suspend/resume session at
the plumbers conf (which follows directly) would probably achieve a
fairly sizeable crossection of unfixed laptops and possibly quite a lot
of bug fixing ...
