grub2, PXE boot, and freebsd 9.1

[Richard A. Sitze]

Greetings list,

I'm trying to use grub2 v 2.00
to facilitate booting FreeBSD 9.1
from a PXE server.

I've configured my DHCP services, and the PXE client is pulling 
"grub.pxe" file from the server and running that just fine.  It fails 
immediately.

My boot screen looks like this:

*****************
* CLIENT MAC ADDR: ....   GUID: ...
* CLIENT IP: 192.168.0.15   MASK: 255.255.255.0   DHCP IP: 192.168.0.1
* GATEWAY IP: 192.168.0.1
* Welcome to GRUB!
*
* error: disk `tftp,192.168.0.1` not found
* Entering rescue mode...
* grub_rescue> set
* net_default_server=
* net_pxe_boot_file=grub/grub.pxe
* net_pxe_ip=192.168.0.15
* net_pxe_max=...
* prefix=(tftp,192.168.0.1)/grub
* pxe_default_server=
* root=tftp,192.168.0.1
* grub_rescue> insmod normal
* error: disk `tftp,192.168.0.1` not found
* grub_rescue>
*****************

Things work just fine with the same system hardware using grub2 v 1.99.

Any ideas on what's wrong at this point, and how I can fix it?
