Reinstalling grub should only be necessary as a last resort.  You are 
not *supposed* to have to do anything after making changes to your 
grub.conf text file (so long as you haven't changed the physical disk 
drive its on).  I don't use a splashimage, you might want to try and 
comment that out, and increase the timeout to something larger (like 
30?) to give you enough time to look at the screen before it defaults to 
the 1.521 kernel....

You also might try changing the default line to default=1 and see if it 
boots the 1.494.2.2 kernel....  Is the 1.494.2.2 kernel still installed?

You might also want to consider removing the "rhgb quiet" options until 
you get this sorted out....

Very strange indeed.  Having a kernel installed (or not) should have no 
effect on Grub since is runs before any kernel gets loaded.

Come to think of it, if none of the above helps, perhaps you *should* 
run grub-install again (and check for any errors).
