@adrimaxi: The instructions in #22 are still correct for 10.6.4 as you have to start with 10.6.0 SnowOSX disc. I've been keeping them updated as we go. I haven't tried installing using a vanilla install disc yet because I haven't needed to.

If anyone does try using a vanilla disc with the kext bundle (and/or DSDT) I've provided I'd like to hear about it so I can try it myself and update the instructions.
