Description of problem:
Trying to boot elf-memtest86+-4.10 from grub fails with
"Error 13: Invalid or unsupported executable format" if I install the x86_64 rpm. Installing the i686 rpm instead works fine (the x86_64.rpm has always contained 32bit binaries anyway).

Version-Release number of selected component (if applicable):
memtest86+-4.00-3.fc13.x86_64
memtest86+-4.10-2.fc13.x86_64

How reproducible:
Always

Steps to Reproduce:
1. Install memtest86+.x86_64
2. run /usr/sbin/memtest-setup
3. Reboot and choose Memtest86+ in grub
  
Actual results:
Error 13: Invalid or unsupported executable format

Expected results:
memtest86+ runs

Additional info:
In Fedora 12 (and the Fedora 13 .i686.rpm), the memtest and elf-memtest image files are about the same size, and elf-memtest works. In Fedora 13 x86_64, elf-memtest is about 1MB larger, and doesn't work.

This is possibly due to the version of binutils in f13 - I built memtest86+-4.10-2.fc13 on Fedora 13 x86_64 but using binutils-2.19.51.0.14-37.fc12, and memtest and memtest.bin end up about the same size (but I didn't test them).
