Hi Mark,
You need to watch the use of fdisk on any OS other than MacOS/X here - the fdisk
partition table is generated from the EFI/GPT partition table by MacOS/X.
So you would need to make the change on MacOS/X, to the EFI/GPT partition table.
The following blog provides a lot of what's needed to achieve the dual-boot:

Another (but I can't remember which - it's been almost 2 years since I did this
last) suggested moving the fdisk binary to one side and replacing it with a
script to ensure there was no attempt to modify the MBR, something like:
# mv /sbin/fdisk /sbin/fdisk.bin
# cat > /sbin/fdisk <<_EOF
#!/bin/sh
if [ "X$1" = "X-F"; then)
exit 0
;;
fi
exec ${0}.bin ${1+"$@"}
_EOF
# chown 755 /sbin/fdisk
I really wish it was simpler...
HTH,
Darren.
