Sound, Encryption (LUKS), Wireless on a macbookpro6,1 in Fedora 12

I've got sound, LUKS, and wireless working on my macbookpro6,1 in Fedora 12 now!

Sound:
Create a file in /etc/modprobe.d named sound.conf with the following contents.

options snd-hda-intel model=mbp55

That'll get sound working over your external speakers. Fire up `alsamixer -c0`.
Unmute and turn up the volume on all the surround mixers to get your internal speakers to work. You can automate this on boot until the kinks are worked out.

Encryption:
You can set up boot time encryption during install but the system won't boot without a change to the kernel parameters. My understanding is there's a problem with the kernel code that talks to the hardware encryption chips. Add the following to the end of your kernel params at boot time after install and also in /etc/grub.conf.

rdblacklist=aesni-intel

Wireless:
Enable rpmfusion (you'll need it for mp3s, aac anyway): http://rpmfusion.org/Configuration

Install with the following:

yum install kmod-wl

Reboot and you'll see NetworkManager pick up the changes.
