Setup the mactel-support package source. In System > Administration > Software Sources, on the Third-Party Software tab, add:

deb http://ppa.launchpad.net/mactel-support/ubuntu jaunty main

Then download the software:

sudo apt-get update && sudo apt-get install install xserver-xorg-input-synaptics bcm5974-dkms applesmc-dkms mbp-nvidia-bl-dkms isight-firmware-tools

Install the kernel modules:

sudo modprobe mbp_nvidia_bl
sudo modprobe appletouch
sudo modprobe applesmc
sudo modprobe bcm5974

Then make sure the modules get loaded again after a reboot with a sudo gedit /etc/modules

# /etc/modules: kernel modules to load at boot time.
#
# This file contains the names of kernel modules that should be loaded
# at boot time, one per line. Lines beginning with "#" are ignored.

loop
lp
rtc
mbp_nvidia_bl
applesmc
appletouch
bcm5974

Make the mouse go faster and turn on two finger click to right click:

sudo apt-get remove mouseemu
sudo gedit /etc/hal/fdi/policy/appletouch.fdi

Reload the appletouch kernel module to activate the new touchpad settings:

sudo modprobe -r appletouch && sudo modprobe appletouch

Get an updated version of the wifi kernel module for the Atheros AR5008 to improve the problems with a weak signal on the default install: sudo apt-get install linux-backports-modules-jaunty

Make the laptop sleep when the lid is shut in System > Preferences > Power Management.

If you didn't already get the window open on you, System > Administration > Hardware Drivers will help you enable the proprietary Nvidia drivers. Version 180 seems to work for me so far.

Setup Medibuntu.

Switch the boot screen theme from Ubuntu to Xubuntu: sudo apt-get install startupmanager

Helpful doc on setting up Eclipse PDT.

I was totally unable to use the "Screens and Graphics" utility that came with Gutsy Gibbon Ubuntu to setup my dual-chip Quadro NVS 440 card for two monitors. I made my own config in the end.
