Wow! He must have sent the message magically!

But back to the original poster -- following the link Chris Mohler
supplied does contain relevant information (you will need to use
ndiswrapper and the driver from the Windows side of the Mac OS
installer disk). BUT the forum has moved since that thread started.

For additional information regarding your Apple hardware, you will
want to check the (new) Ubuntu Apple Users forum. The Apple forum may
be better than this list for getting Apple-specific installation
advice.

There's also a wiki page where folks have collected some information
relevant to installing Ubuntu on a MacBook Air

https://help.ubuntu.com/community/MacBookAir1-1/Intrepid

(If you just downloaded the latest version, you probably have Ubuntu
9.04 "Jaunty," but many of the tips will probably still apply. If not
you could add additional tips to that page as you discover them.)
