Both Rui and Andrey should be able to to fit your need for mentors.
I can help with some stuff. It seems you've looked at the Mac side
a fair amount. It might be good to look at X64 and IA64. Don't know
how much can be shared. There is an efi loader in the tree for IA64.
I've only played around with generic PC's (Dell, AMI based systems
and qemu). I built grub and had grub boot via efi.
