[rescue] Sun 3/110 Netbooting -- An update

Howdy folks,

Well, making some (I think) progress on getting the Sun 3/110 to netboot.
Here's where I am now.

1) Got a NetBSD virtual machine running on my Mac (NetBSD 6.1.4)
2) Got it configured for Netbooting (after following the mostly correct,
and mostly complete configuration)
3) Sun 3 "starts" to boot from NetBSD.

However, not "quite" booting (but seems close...)
It gets the RARP info... and starts downloading the kernel...
Then I get what looks similar to the boot I'm familiar with...(I've got it
typed in below)

Model: sun3 110
fpu: mc68881
total memory = 8192 KB
avail memory = 6744 KB

obio0 at mainbus0
zsc0 at obio0 addr 0x0 ipl 6: (softpri 3)
kbd0 at zsc0 channel 0: baud rate 1200 (console input)
ms0 at zsc0 channel 1: baud rate 1200

zstty0 at zsc1 channel 0 (console i/o)

obmem0 at mainbus0

cgfour0 at obmem0 addr 0xff300000 (1152x900)
enabling interrupts
boot device: <unknown>
root device:

 -- So I'm now at a place where it doesn't look like it knows where the
boot device is.
It boots of ie0 (the 3/110 doesn't have an le0) and the other examples I've
seen here it shows it detecting a le0 device.
So is it simple the wrong kernel (or is missing le0 device info?)
