Renaming the boot selection dialog items

I have an interesting question for a propeller-head out there.

I have successfully installed Ubuntu on my Intel iMAC and been using for those few things that MAC just won't do for me, so far.

But is has always bugged me that when I hold down the option key at boot, my choices are Mac X or Windows.

Now I do have Windows onboard as a VMWare appliance, but not as boot partition.

How do I get the splash menu to read Ubuntu instead of Windows?

I know that MAC has Unix roots as does Linux, but just can't find a grub-like or lillo-type boot-menu file to edit.

Can you help me?

Yours,

RC

I'm not sure how to accomplish this for the Boot Camp menu (actually, I'm not exactly sure it's even possible right now) but if you install rEFIt you can boot to either of your partitions without having to even hold down option at boot.
