I just did that conversion today, IIRC for the 2nd time in 3 or 4 years, and 
did not have to rebuild anything other than making sure all the I's were 
dotted and the T's crossed in both /etc/fstab and in /boot/grub/grub.conf.  
No vmlinuz or initrd rebuild was required. But since I was moving the drive, 
I did have to grub-install /dev/sda twice before it worked.
