Yes, I had seen this and tried it - it was his guess and did not work.

I finally got it to work - this is not documented anywhere so I will paste it in here for the next 
guy. You only need insmod lvm and jfs if you are using lvm and jfs ... your "set root=" will differ 
as well the directory paths. In /boot I put a ln -s /usr/lib/syslinux/memdisk ,but one could use the 
full path.

This is for grub2 - not grub. Located in /etc/grub.d/40_custom (you need to run update-grub after 
any changes )

exec tail -n +3 $0

menuentry "Memtest-Plus 4.2" {
         echo `hello`
         insmod lvm
         insmod part_msdos
         insmod jfs
         insmod memdisk
         set root='(ssd-testing)'
         search --no-floppy --fs-uuid --set f9ae292b-b6a9-4f70-af7c-31987e766d37
         linux16 /boot/memdisk iso
         initrd16 /boot/memtest-plus/memtest86+-4.20.iso
