Hi Cam,
First off that is one beautiful TV you have, colour me green.
As far as I know the VESA specs apply to the distance between mounting holes, depth of mounting holes, and the weight that the mount will hold. I wouldn't recommend a VESA mount for a non-VESA spec tv, if there was any damage to the TV I think you would be out of luck with the warranty.
I don't understand why all manufacturers do not adhere to this spec... other than the the fact that they would like to sell you their overpriced mount.
Sorry, I haven't been much help, a post on AVS may be of more benefit, good luck.
