Grub 2 error: unknown filesysetem

Partition setup (for my macbook5,2):
/dev/sda1  is an EFI partition
/dev/sda2 is the main macbook partition
/dev/sda3 is my swap partition
/dev/sda4 is my arch linux root partition (ext3)

Whenever I try to boot from my arch partition I get 'error: unknown filesystem' and am shoved into a rescue terminal. I am not sure what to do. I have seen people's /boot/grub/grub.cfg files and they look very different from mine. (I retyped my grub.cfg file by hand so there could easily be some errors. Tell me about them anyway though!!!)

Grub 2 worked fine in Linux Mint so I know it will run on my computer. Grub Legacy has serious problems with macbook that nobody has been able to solve so I can't use that. I added the 'Arch Manual entry to try and solve this but it didn't work. (acpi has to be off on the macbook as far as I can tell). Any suggestions?
