I tried it with IOATAFamily from Leopard, made all my IDE Drives (Target drive is SATA though) show up, but then crashes because of kextcache, as you can see in the attachment.

Could it have something to do with the fact that the Extension in Extra don't have an Extensions.mkext?

UPDATE:

Now I am completetly confused. Tried it several times now, and everytime the cause for the kernel panic is a different one....I had kextcache, Mac OS X Installer and kernel_task cause kernel panics at the exact same step and once just after booting into the installer and letting the computer sit idle for like 10 seconds.

64Bit kernel panics way before even reaching the GUI....

BTW: I made sure all the UUIDS are correct, it panics anyway.
