Frakked MBR! No Darwin Bootloader and HD is non-Bootable!

[FullMetal]

Here's my situation.

 

The other day I decided to install Ubuntu 5.10 on my 30GB Hard Drive listed in my Sig. It installed fine and booted straight into Ubuntu, but all was not well! During the installatioin Ubuntu repartitioned my OSx86 drive and erased both my MBR and the partition that had Darwin on it and in their place installed Grub.

 

I decided to setup Ubuntu and then try to setup a Grub dual-boot. Sadly I ran into a freaking ton of errors, one of which was my inability to go into super-user mode, and since I couldn't become root I couldn't edit grubs config file and I couldn't boot into OSX.

 

I tried everything that I could with Linux (I even reinstalled it twice), but I came up empty every time. I eventually erased my linuc drive and erased my mbr. I'm currently booting using my osx install dvd, but it takes much longer to boot and its quite agrevating!

 

I've tried to fix my problem, but I can't so I need help.

 

Here's some info on my drive:
