Gary, I would highly suggest you look at my github
. I have a device tree for the p6210 that I try to keep up to date, but I'm already doing all the building for the p6800 and p6810 builds, so I don't really have spare cpu time to build for the p6210.
Also, I just managed to get wifi working -- a modification is needed to a CM repo. I haven't posted a changeset to review yet since I'm still tinkering with a value. Let me know if you need/want help. Aorth and I are on #teamhacksung most of the time, so you can aways get a hold of us there.
And yes, it is the 2.6.36 kernel. We need to fix ics gadget support (I have a branch starting that), and probably other stuff. Our wifi module is compat-wireless-3.3-rc1-2 (same as the new touchpad module), plus sdio from the galaxys2 ics source drop. I would like to try to get the teamhacksung smdk4210 kernel working on our devices, but I haven't gotten around to making a uart cable to debug it.
