Sorry, scratch that. Seems to have taken using the following commands:

nm

[[nikm@bigmac /]# pdisk -i
Top level command (? for help): ?
Notes:
  Disks have fake names of the form /dev/scsi<bus>.<id>
  For example, /dev/scsi0.1, /dev/scsi1.3, and so on.
  MkLinux style names are also allowed (i.e /dev/sda or /dev/hda),
  and these names follow the MkLinux DR3 conventions.

Commands are:
  h print help
  v print the version number and release date
  l list device's map
  L list all devices' maps
  e edit device's map
  E (edit map with specified block size)
  r toggle readonly flag
  q quit the program
Top level command (? for help): E
Name of device: /dev/sda
A logical block is 512 bytes:
pdisk: No valid block 1 on '/dev/sda'
Edit /dev/sda -
Command (? for help): q
Top level command (? for help): E
Name of device: /dev/sda
A logical block is 512 bytes: 512
pdisk: No valid block 1 on '/dev/sda'
Edit /dev/sda -
Command (? for help): i
A physical block is 1 bytes:
A logical block is 512 bytes:
size of 'device' is 4194058 blocks (512 byte blocks):
new size of 'device' is 4194058 blocks (512 byte blocks)
Command (? for help): p

Partition map (with 512 byte blocks) on '/dev/sda'
 #: type name length base ( size )
 1: Apple_partition_map Apple 63 @ 1
 2: Apple_Free Extra 4193994 @ 64 ( 2.0G)

Device block size=512, Number of Blocks=4194058 (2.0G)
DeviceType=0x0, DeviceId=0x0

Command (? for help): w
Writing the map destroys what was there before. Is that okay? [n/y]: y
The partition table has been altered!

Command (? for help): q
Top level command (? for help): q
[[nikm@bigmac /]#
