What about drivers for gfx, sound, chipset, WLAN, AMD support... I can imagine especially gfx is problematic if AppleTV is still Tiger-based and newer cards are only supported in Leopard.

No it won't be...
It is a Leopard kernel built for AppleTV (unlike the standard 792.XXX.XXX kernels for AppleTV)
It will support also the newer kexts and run the rest perfectly...
The other kexts will work (because of compatibility) and the rest will run perfectly as well...

Without further delay I announce:
The AppleTV OS kernel...
Get it from:

AppleTV
 

I will try it as soon as I get home! At college at the moment. Thanks Andy,

No problem... ;)

If this get's AppleTV to run on your machine, PLEASE let us all know exactly how you get it to run. This is epic if it works.

Maybe you should add a modded version: AndyTV :D

If anyone has a suitable installer this would be great. Do you think it would work from an USB stick or an USB harddisk?

I think the plan is to build it into a pkg and add it to a Leopard DVD, to make a modified installer.. once its up and running that is..

How are the tests progressing?
Any luck on making it boot properly?

Booting
 

Hey Andy, I'm off to bed now.. exhausted! Will be having a play tomorrow :) If I can get this damn prelinked kernel working.. Will see how far I can get by just putting kexts in /S/L/E..

Laters, will keep you informed.
