With GRUB2 you don't have to add anything. /etc/grub.d/39_memtest86+ is
created by the ebuild, containing slightly less than 300 lines

#!/bin/sh
exec tail -n +3 $0

menuentry "memtest86+ 4.20" {
        linux16 /boot/memtest86plus/memtest
}

menuentry "memtest86+ 4.20 (netbsd)" {
        insmod bsd
        knetbsd /boot/memtest86plus/memtest.netbsd
}

This is added to your menu automatically by grub2-mkconfig.

This is one of the great things about GRUB2, it allows install scripts,
whether they are package installers or complete distro installers, to add
to your GRUB menu without disturbing, or even needing to know about, your
existing configuration.
