There's been a lot of fragmented discussion about developing kernels for these SoCs, including a big thread of comments on my previous blog post.
So I've decided to create a Google Group to act as a mailing list for people interested in Linux kernel development on these devices: http://groups.google.com/group/vt8500-wm8505-linux-kernel.
This is intended for people interested in hacking on the kernel. If you're interested in just running Linux on VT/WM netbooks, there is bento-linux and their forums. For tablets, there is slatedroid.com. Both are great communities.
