[PC-BSD Support] Grub can't find PC-BSD's partition

[Aniruddha]

I installed PC-BSD on a spare harddrive. I didn't opt for a bootloader
since I have multiple OS'es installed (Gentoo, Debian etc.). Therefor I
use GRUB to boot PC-BSD.

Before I installed PC-BSD I had FreeBSD installed on the same partition
which booted fine. I replaced FreeBSD with PC-BSD and unfortunately GRUB
can't find it's partition. Anyone has idea how I can fix this? Here's
some relevant information:

My GRUB entry:
> title  FreeBSD 7.0
> root   (hd2,a)
> kernel /boot/loader

The disk where PC-BSD is installed:
> Disk /dev/sdi: 160.0 GB, 160041885696 bytes
> 255 heads, 63 sectors/track, 19457 cylinders
> Units = cylinders of 16065 * 512 = 8225280 bytes
> Disk identifier: 0x8f8000b1
> 
>    Device Boot      Start         End      Blocks   Id  System
> /dev/sdi1   *           1       14358   115330603+   7  HPFS/NTFS
> /dev/sdi2           14359       16908    20478976    7  HPFS/NTFS
> Partition 2 does not end on cylinder boundary.
> /dev/sdi3           16908       19457    20477803+  a5  FreeBSD
> Partition 3 does not end on cylinder boundary.
