Loading memtest from grub (Fedora)

Programs started segfaulting for no good reason every now and then on my Thinkpad X61s running Fedora 14. So I turned to memtest86+, and it's easiest to just run it from Grub at boot (especially if you're lacking an optical drive or the ability to boot from a USB stick!).

memtest86+ might be installed by default; if not, run yum install memtest86+. Run /usr/sbin/memtest-setup to set up a grub entry. The following was added to my /boot/grub/grub.conf:

title Memtest86+ (4.10)
        root (hd0,4)
        kernel --type=netbsd /elf-memtest86+-4.10

All done. Reboot, start memtest and do something else for a while.
