[x-posted back to netbsd-users for posterity]

I've managed to chainload the efi boot files from Grub2.

Recap: on my system (hd0,gpt2) is the second partition containing all
the EFI boot files (NetBSD, Linux and Windows); (hd0,gpt5) is the
NetBSD partition.

Steps on Linux:

- Become root;
- Add these lines to /etc/grub.d/40_custom

menuentry "NetBSD" {
        insmod part_gpt
        insmod chain
        set root=(hd0,gpt5)
        chainloader (hd0,gpt2)/EFI/boot/bootx64.efi
}

# update-grub2
# reboot

The chainloader will go and find the "bootx64.efi" file in the second
partition. No need to have an efi dedicated partition in the NetBSD
wedge.

A "NetBSD" entry will appear on the Grub splash screen.

Enjoy.

Feel free to put that somewhere in the wiki or I can add that to an
existing page as a comment.
