It might very well be, that I'm mixing things up here, that's why I
asked for clarification.

I don't know, if Debian has any modesetting patches backported, but I doubt it.

Going back to the original bug report I referenced, you see that the
bug reporter was running a 2.6.26 kernel and has a 915 hardware.
Apparently he still requires the vbe* quirks to successfully suspend and resume.

So, is there something within pm-utils that has to be done about this
or is this a kernel bug?
