Here you see the Ubuntu login screen an a MacbookAir3,1.
Basicly the installation is similiar to a normal installation, the first thing you have to do is :
1.) Use nomodeset as boot option for the installer.
On the first boot add nomodeset and reboot=pci to the kernel parameters.
How to make this permanent look at this wiki page :
https://help.ubuntu.com/community/MacBookPro7-1/Maverick
I also used the sound config from there.
For the keyboard and touchpad you can use this patch :
macbookair_patch_2.txt
Edit /etc/initramfs-tools/modules and add :
bcm5974
hid-apple
usbhid
