[Openchrome-users] VIA CX700M HDMI 720P Output Fail

[Dan Kingdon]

Hi, 
Running a brand new Jetway J7F5M-VHE motherboard with HDMI output, Ubuntu 9.04 Desktop, bundled openchrome drivers. 
Ultimate goal is to get full 1280x720 via 720P HDMI to a plasma TV. 
At present its not having any of it and I am strugling to find any info on anyone who has. 
With mother board set at "CRT+HDMI" and default xorg.conf I get a perfect picture on the CRT and a picture on the HDMI which is clearly not in a proper mode, no matter what the resolution. Colour appears to match the desktop but is flickering and out of sync. 
With the mother board set at "HDMI" we get the same garbled mode on the TV. 
Switching to openchrome drivers, we can get a picture on the HDMI cable but it is running at a fixed res and any resolution set in xorg.conf merely underscans and is cropped.
Adding any of these options does not seem to effect things. 
Option "TVOutput" "720P" 
Option "TVType" "Composite" or Option "TVType" "SC" or Option "TVType" "HDMI" 
Adding Option "ActiveDisplay" "TV" casues X to fail to load and sticks at flashing cursor. 
Adding Option "VBEModes" Also causes X to hang at flashing cursor. 
1. Does anyone have HDMI output working on this chipset? If so do they have a working xorg.conf file that I can check out.
2. Has anybody had better luck on other linux distro's? Fedora seems to be the manufacturers favourite. 
3. Any help very much appreciated. (if all else fails then we shall have to use windows :( ) 
Thanks for reading.
