OMV on Jessie/ Haswell iGPU on Wheezy?

Hi guys,
is there any chance that an early OMV version with Jessie will be available soon?

Background why I ask this is the following:

I want to build a NAS/HTPC-Combination(basically just an XMBC running on the server to watch film/series directly) with OMV.
Unfortunately it seems that my Haswell iGPU is too new for wheezy. So I'm getting >90% CPU Load on all cores while just navigating in XBMC and of course also while playing a film.
I already tried different things to get it working (Backport drivers, compiling the drivers by myself like it's shown here http://forums.debian.net/viewtopic.php?f=6&t=84825) but XBMC always uses just gallium driver instead intel (yes I have the right drivers installed). Xorg always is able to load the intel driver but later fails when setting up the AIGLX stuff:

[    32.834] (EE) AIGLX error: Calling driver entry point failed
[    32.834] (EE) AIGLX: reverting to software rendering
[    32.861] (II) AIGLX: Loaded and initialized swrast
[    32.861] (II) GLX: Initialized DRISWRAST GL provider for screen 0

So is there any hope to get OMV on Jessie soon (there Haswell iGPUs are reported to work)?
Or does even someone have a brilliant idea how I could get it working on Wheezy? (I'll post more details on request, don't want to spam this forum with gpu driver stuff now)

Thanks

I mean backports kernel and xserver-xorg-video-intel from backports. The vaapi stuff (libva1, libva-intel-vaapi-driver) is unfortunately not available in newer Versions in Backports, but I think they are the stuff I need in a slighly newer version (libva-intel-vaapi-driver is available in 1.0.17-1 and haswell support is in there from 1.0.19 ). I tried to compile libva and ther vaapi-intel driver by myself as described in the link I posted before, but didn't got it to work so far.

But thanks for your answer.
