Try this: plug your HDD's into SATA 1&2 (maybe I'm just paranoid, and think that everything can go wrong?) and the DVD into 3. Then set C-States to C6 and cores to All and activate EHS. Then try to boot with Empire EFI.
Edit: My kexts are
fakesmc (because we all need it)
IOAHCIBlockStorageInjector (orange icon fix)
IONetworkingFamily (for RealtekR100 dependencies)
JMicronATA (?? SATA or my IDE drives, I get a KP without it)
LegacyHDA (for ALC890 HDA audio)
RealtekR100 (for ethernet).
So it would seem that fakesmc and JMicronATA would suffice for booting.
