Finally we see some progress here Now that we know what's the problem the solutions would be :

FIRST OF ALL ! Please make sure again that in your bios/sata configuration is set to AHCI !


If is set to AHCI, then I think your problem is your Hard Disk device id, not listed in IOATAFamily.kext. Please try with the one below (thanks to Edge3000)

This is a SNOW LEOPARD IOATAFamily.kext with dev id's copied from Leopard's IOATAFamily.kext
Also (just making sure ) after you copy this one in /Volumes/SL/System/Library/Extensions/ type again the chown and chmod command.

and boot with -f -v to be sure is loading

Let us know
