Macbook Strike One: Keyboard Failures During Bootloader

Bootloader keyboard issues (GRUB in particular) are an Apple Bug according to the the Refit folks back in March. Dual booting is pretty painful, if not impossible. Workarounds, create a custom isolinux image while you are testing kernels or just keep rebooting until probability catches up with you and you can actually use grub to select a kernel/os. No thanks, I'll pass.
