What error?  (You didn't mention one before.)

Also, you might try using the rpm command, unless you'd rather not. ;)

I am not sure what the status of grub2 is -- and as I said before, I'm a 
grub2 noob.  ;)

But you can find out the version of grub installed on /dev/sda with:

# file - < /dev/sda

(You need the dash to tell file(1) to read from stdin).

Is the error you mentioned earlier from dracut?  Might want to check to 
ensure you have one (and only one) dracut installed:

$ rpm -qa | grep dracut
dracut-013-18.fc16.noarch
