That looks correct.  but check grub.conf to make sure the kernel file 
you're trying to boot is the correct one.

Also, remember that it will look a little funny, if you have a separate 
/boot partition -- the filenames will be in the "root" directory, like this:

title Fedora (2.6.35.10-74.fc14.x86_64)
     root (hd0,0)
     kernel /vmlinuz-2.6.35.10-74.fc14.x86_64 ro 
root=UUID=69effc7d-ef6e-4982-9bdc-2f3bea9e056e rhgb quiet 
SYSFONT=latarcyrheb-sun16 LANG=en_US.UTF-8 KEYTABLE=us selinux=0
     initrd /initramfs-2.6.35.10-74.fc14.x86_64.img

It's the kernel line I'm referring to, it will be "/vmlinuz-..." instead 
of "/boot/vmlinuz-..." -- but _only_ if /boot is a separate partition.

Quick question -- if it _doesn't_ boot, can you afford for this system 
to be down until it can be fixed?
