that's how i got it to work

use Vmware 6.5 (at least)
set up a new vm using FreeBsd (32 or 64 bit both should work)
network bridged
1 Processor (1core)
HDD (IDE or SCSI both should work,look wht's better for you)
and save it.

now open the .vmx you created and change the value
"guestOS = "FreeBSD"
to
"guestOS = "darwin"

and may be the .encoding = "windows-1252"
to .encoding = "UTF-8"

now it should start the setup, when getting Kernel Panics try
-v cpus=1 busratio= [your busratio here]
