Same here. I have been trying to figure out why my Acer TM6460
suspended/resumed fine on FC6 and fails miserably on up-to-date F7. So
far I have figured out that it needs to suspend with:
# pm-suspend --quirk-s3-mode

I have seen the blank screen thingy before. This webpage has quite good
tips how to go about fixing it:

On an Acer Ferrari 4005 with FC6 it was solved by unloading/blacklisting
pretty much every module. Unfortunately that trick does not seem to work
(so far) on my Acer TM6460.

This page has some good tips how to analyze the possible culprit:

Dunno but with the fast & furious pace of kernel development regressions
are almost inevitable. That's ok as long as they get fixed at the same
pace.

Yup, same here although my laptop is a bit newer.

I don't really see grandpa messing with unloading modules and pm-utils
quirks until he gets suspend/resume working. But if we can all submit
the information that made it work on our laptop than we can hopefully
make sure that grandpa gets a working setup out of the box with F8:
