The /etc/grub.d/memtest86+ must use the linux16 command now.
and that file is provides by the memtest86+ package, not at all by the
grub2 ones.
It's impossible to load it with the linux command.
memtest86+.bin doestn't provide the 32bit booting protocol recent Linux
kernels have.
It even still uses zImage format and not the bzImage one, which was
introduced with kernel 1.3.73.
Or they could just implement multiboot, but then the linux command needs
to be changed to multiboot.
Robert provided a patch though for memtest86 without + to implement
multiboot.
As I already said in my grub-devel mail:
> zImage doesn't suppoert 32-bit boot (try with linux16)
grub tells you.
Use linux16 /memtest86+-2.11.bin
