What about these (together):-
--quirk-dpms-suspend
--quirk-dpms-on
--quirk-vbestate-restore
--quirk-vbemode-restore
--quirk-vga-mode3
--quirk-vbe-post

AFAIK they won't, unless the problem is a buggy BIOS

Sapphire Radeon R7 240 ??
I've installed both the FOSS (radeon) and non-free (fglrx) driver for it
in the past - so vesa would not be necessary. I had to install
fglrx-driver and fglrx-control from testing at the time (over a year
ago) - but the Wheezy or Wheezy backports packages should work fine.
You'll need non-free repositories enabled in /etc/apt/sources.list.
I'd previously installed the FOSS radeon driver (and found it too slow)
which meant I had to blacklist that module to get the Closed Source
driver working - from all reports the card still works very well.
I included the fglrx-modules-dkms to get 3D-accellerated graphics.
The process is documented here (though I used a different method):-
https://wiki.debian.org/ATIProprietary#Debian_7_.22Wheezy.22
I'd suggest installing the proprietary driver unless you're happy with
vesa - or, quite reasonably, reject closed source software (in which
case you might have bought a less powerful card).
NOTE: I've only dealt with suspend and that card when dkms was used.
The FOSS radeon driver installation process is described here (a little
dated?):-

A reference for Suspend is here (note that the information about dkms is
out of date):-

A reference for debugging Suspend is here:-

Questions:-
Anything useful in /var/log/pm-suspend.log ??
What sort of keyboard ??
Is it a USB keyboard ??
Was Wheezy a fresh install or did you upgrade from Squeeze ??
What sort of desktop is it (make/model) - if a no-brand, what is the
motherboard ??
Could you please paste your /var/log/Xorg.0.log somewhere e.g.
paste.debian.net and post the link in your reply ??
HINT: pastebinit is a useful debian package for just that purpose
Kind regards
