Author Update #1 @R:A:W:X86 2012-07-26

We will see what can be done, once the source code is released...

Comparing the Kernel with the Lion one in ida looks like Apple has made quite a lot of changes to the gear unit.

Most likely AMD ain't impossible - but it may require some serious rewrite of a patch.
People have been booting the x86_64 Kernel in Snow Leopard, but I haven't ever seen it up and running. Furthermore the current Lion patch contains a lot of obsolete code changes that last from Voodoo XNU and even earlier - it would deserve some update anyway...
But I don't think I'd be able to do such a job.

I am running Mountain Lion on MBP and Xeon Workstation - very satisfied so far...

Field Note #1 @Jonnes 2012-07-26

When did you make kernel for 10.8? I'm very exciting. But Apple haven't opened latest xnu source.
And the price became cheaper…

Field Note #2 @Unrealized 2012-07-28

Bought Mountain Lion too, haven't had time to install it yet though

Nawcom released a Snow Leopard kernel. It can launch with 64 bit. I don't think AMD is impossible, but it will only support some AMD cpus.
It's difficult,not impossible.

Field Note #4 @Unrealized 2012-07-28

Heh, setting up a Snow Leopard VM so I can set up the USB stick needed for Mountain Lion setup. We'll see how it goes.

Field Note #5 @fxspec06 2012-07-28

I've got a question:

Is there any way to get the updated video card drivers from 10.8 (i.e. 77xx series) working in 10.7?

May be a misunderstanding of the drivers.
