Description of problem:
grub2-mkconfig fails to find the initrd for kernels with names ending with ".old".  Such kernels appear when a self-compiled kernel is installed and a kernel of the same version is already installed.

Using the new initrd with the old kernel is better than using no initrd at all.  The later simply fails to boot, the former is likely to work somehow.

Version-Release number of selected component (if applicable):
grub2-1.98-3.fc14

How reproducible:
Always

Steps to Reproduce:
1. compile kernel and install it
2. install the kernel again
3. run "grub2-mkconfig -o /boot/grub2/grub.cfg"

Actual results:

Generating grub.cfg ...
Found linux image: /boot/vmlinuz-3.0.0-rc5+
Found initrd image: /boot/initramfs-3.0.0-rc5+.img
Found linux image: /boot/vmlinuz-3.0.0-rc5+.old

Expected results:

Found linux image: /boot/vmlinuz-3.0.0-rc5+
Found initrd image: /boot/initramfs-3.0.0-rc5+.img
Found linux image: /boot/vmlinuz-3.0.0-rc5+.old

Additional info:

grub-1.97.1-initramfs.patch should look for both "initramfs-${version}.img" and "initramfs-${alt_version}.img"

Upgrading GRUB 2 to version 1.99 or newer should resolve the problem automatically.
