So I actually managed to get Snow Leopard to work on my EeePC 1000HE. I've installed the Chameleon 2.0 RC4 boot loader, other than that, no hacks, patches or anything. I was surprised to find the wireless, battery status, sleep mode, webcam, microphone and everything else working right...
This is a graphic I put together for one of my blog entries: addendum.dview.us/post/110837839/say-hello-to-my-new-litt...
I used the ASUS stock Eee PC photo (with a blue screen) as a base, and worked from there.
