Video working after a hibernate/thaw cycle is the usual thing -- the
BIOS fully reinitializes the video hardware when you boot the system to
wake up from hibernate, so we don't have to with the various quirks.

Hmmm... I am not parsing this correctly.  Are you trying to say that you
are able to suspend/resume using s2ram or pm-suspend only after a
hibernate/thaw cycle, or something else?

Hmmm... vanilla pm-utils does not use S2RAM_OPTS.  What distro and
revision of pm-utils are you using?

pm-hibernate and s2disk don't do any handling of the video card at all
by default.

Nope.
