There are plenty of references to "Error 28: Selected item cannot fit into
memory"
on google:

In fact, I think memtest86 is supposed to be run using a floppy, a CD-Rom
or a Pen-drive. Adding an entry in grub.conf for booting from the HD
is something Linux distributions have done so users may only reboot
and choose memtest86 from the boot menu.
Therefore, this is an issue we have to deal with by
ourselves, because grub is not an upstream's problem.

Unless I am missing something here ....
