The WM8505 Android 1.6 release has some custom hacks in the UI library layer to work with their video hardware.
Since VIA released Linux kernel source for this SoC a few months ago, some other people have successfully worked out more about the graphics driver and started developing an alternative kernel from scratch[1]. With this understanding, the possibility of the community porting Froyo is higher than it was before.
However, AFAIK noone has really put strong effort into it. One of the reasons I lost interest is that 128Mb of RAM is apparently not enough to run 2.2 decently regardless, and that's all most of the tablets have. If this one has 256Mb then it might actually be up to it.
