Matt:

I purchased a New Apple MacBook Air today:

After a little fiddling , I got your

 http://people.sugarlabs.org/Tgillard/soas-3-boot-test.iso

To work with a 2GB USB script installed soas-v3-Mirabelle USB
I found that the USB booted but the graphics caused a very 
distorted/smeared image.
After I did the folowing changes' it boots fine:

Method:
Take the Mirabelle USB and mount it in a Linux Box. Open the USB;
edit the 4 files in it (attached) to match:

Fedora/EFI/boot.conf
Fedora/EFI//grub.conf
Fedora/EFI/isolinux.cfg
Fedora/syslinux/syslinux.cfg

Put the mirabelle USB in the Apple Air USB port
Load the soas-3-boot-test.cd in a External USB CD/DVD drive and connect 
it to the 2nd USB port on the Macbook Air
Hold down the "C" key and press power button. release power button -It 
will make a bong sound- continue holding down the "C" key until you get 
a fedora blue boot screen from the Spinning CD. hit TAB and edit the 
boot line like the CD_boot Menu-changes.jpg show.
  edit out "quiet" and and add "nomodeset xdriver=vesa"
Hit return and the USB will begin boot sequence.
Disregard the ata:COMRESET failed (errno=-16)messages (repeats t least 3 
times)
Eventually the USB will Boot to F3 Ring. (Mirabelle_f3.jpg)

I am sure that all 4 of the .cfg files do not need to be edited and 
saved on the USB, but It does boot the USB into Soas correctly.
Next I have to buy a network adapter, the MacBook Air wireless is not 
recognized by Network Manager....Maybe I should have obtained a Macbook 
with a CD and network Cat5 installed. :  /

Congratulations;

Thanks again for a neat solution;
