I think you need to put the open braces in the same line as "menuentry" commands. > Then grub shows command line interface: > > grub> set root=(hd0,5) > grub> linux /boot/vmlinuz root=/dev/sda5 > grub> boot > grub> _ > > is what I entered and now nothing happens.

I don't know how Gentoo defines the default settings, but most distributions do not enable it in default kernels, AFAIK. - Make sure that the linux kernel has an appropriate video driver (or any other required drivers). Again, I don't know the current status very much, but patches for MacLinux hadn't been integrated with official kernel source code when I looked at it. If Gentoo does not get them included, you need to apply patches yourself. - Make sure that you pass correct parameters to the kernel, especially a parameter to the video driver. Otherwise, nothing will be displayed. Another option is to use legacy boot by installing GRUB compiled for PC BIOS to the partition for Gentoo. I think recent versions of Intel Mac should support legacy boot by default. But, for now, GRUB does not support chainloading a legacy boot loader directly, so you will have to boot it up from the built-in selector, or use something else, such as refit, or implement this feature in GRUB. As I myself haven't played legacy boot well, I don't know how to set up this kind of configuration precisely (yet). BTW, this report seems to be a proof that x86_64 starts up in 32-bit mode even on EFI, well, in Intel Mac. So do we really need to implement 64-bit support for x86_64?
