Grub: Ubuntu + OSX86 over 2 HDDs

[okey666]

This is my current partition layout over two disks (sudo fdisk -l):

 

WARNING: GPT (GUID Partition Table) detected on '/dev/sda'! The util fdisk doesn't support GPT. Use GNU Parted.


Disk /dev/sda: 250.0 GB, 250059350016 bytes
255 heads, 63 sectors/track, 30401 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x00000000

  Device Boot      Start         End      Blocks   Id  System
/dev/sda1               1       30402   244198583+  ee  GPT
/dev/sda2   *           1           1           0    0  Empty
Partition 2 does not end on cylinder boundary.

Disk /dev/sdb: 250.0 GB, 250059350016 bytes
255 heads, 63 sectors/track, 30401 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x00021528

  Device Boot      Start         End      Blocks   Id  System
/dev/sdb1               1       12449    99996561   83  Linux
/dev/sdb2           12450       12947     4000185    5  Extended
/dev/sdb3           12948       20780    62918572+   b  W95 FAT32
/dev/sdb5           12450       12947     4000153+  82  Linux swap / Solaris

 

Which translates as:

hdd0:

-efi

-mac (Kalyway 10.5.2)

-ubuntu backup

 

hdd1:

-ubuntu

-swap

-timemachine (will be soon)

 

I want to boot osx86 using grub, however when using this:

title Leopard 10.5 Kalyway
rootnoverify (hd0,1)
makeactive
chainloader +1

I get "HFS+ partition error"

 

I beleive that this could be to do with the guid partition scheme as grub 1.* does not support and grub 2 won't be used until ubuntu 9.10. Is this correct? I want to make sure before reinstalling.
