I guess you mean from bzr - OK, I'll give it a try

Everything appears as normal, i.e. boots into X, except there is no 
keyboard/mouse

OK - is there any documentation for this specific to grub-efi?

As per above, usb_keyboard was linked via grub-mkimage - the keyboard/mouse do 
not work with/without any usb modules
--------------------------------------
I compiled grub from bzr a couple of days back.

I didn't use grub-install as I'm nervous about writing to the mbr and not being 
able to boot the mac mini at all.

Anyway, I can still boot using both hfs+ partition /efi/grub/grub.efi and fat 
partition /EFI/BOOT/ BOOTX64.EFI, but the result is the same - no usb keyboard 
and no usb mouse.

Note that I also do not get graphics, but it boots "blind" without problems.
