Grub boot loader issues

[rockstar_janitor]

I have a triple boot machine: Windows 7, Ubuntu 10.04 and OS X (snow leopard). My boot loader is grub. Windows and Linux are on the primary drive. The secondary drive is one os x partition. I can use grub to successfully startup windows and linux. However, when I attempt to boot up os x via grub it always states that it can't find the system. When I boot via the kakewalk cd, it finds the os x partition and allows me to boot into it without a problem. Is it even possible to use grub to boot into my system?

 

My current config:

Intel Core i7 Processor i7-930 2.80GHz 8 MB LGA1366 CPU

Cooler Master Hyper 212 Plus

Gigabyte LGA1366 Motherboard GA-X58A-UD3R (Yes, I now it is not supported, but I figured I would give it a try)

G.SKILL 6GB (3 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Triple Channel Kit F3-12800CL9T-6GBNQ

Acer H233H bmid 23-Inch Widescreen LCD Display

EVGA nVidia GeForce GTX260 Core 216-55nm Superclocked 896 MB DDR3 2DVI PCI-Express Video Card 896-P3-1257-AR

Corsair CMPSU-750HX 750-Watt HX Professional Series 80 Plus Certified Power Supply compatible with Core i7 and Core i5

 

Any help would be greatly appreciated.
