You are more than welcome to use the graphic... I created it rather 
hastily, so I'll check to see if the text is centred within the png file.

The command you provided did indeed create a new initrd image, even 
updated my grub.conf file and everything... but upon reboot, no new 
graphic!  I found the following command alone will do the trick:

/usr/sbin/plymouth-set-default-theme rings --rebuild-initrd

The command executed rather fast... so I think it only updated the 
existing initrd instead of recreating it from scratch.

I think it looks better... but I just chose any random font that looked 
somewhat similar to the original.  If there is a specific font/color 
you'd like to use, let me know and I'll make another.
