: QEMU emulates RTL8029:
: 
: ed0: <RealTek 8029> port 0xc100-0xc1ff irq 11 at device 3.0 on pci0
: ed0: Reserved 0x100 bytes for rid 0x10 type 4 at 0xc100

: and Warner Losh MFC'd new ed(4) right before 6.0-RC1:

Yup.  I'm trying to get qemu going here.  It core dumps for me in
-nographics mode, which frustrates me since I can't run it on my
fastest machine while at work (the machine is at home and the DSL line
is too slow for qemu's use of X but not too slow for firefox!).  I've
installed it on my laptop and we'll see how well it works.  I'm
guessing it may be a bug in all RTL80x9 hardware that I introduced
into the patches I committed (or was there from the start).

I lost my bid last night on real 8029 and 8019 hardware on ebay.  If
someone wanted to send it to me, that would be great!  I have enough
other NE-2000 clone hardware (including about 30 16-bit PC Cards that
all work flawlessly or nearly flawlessly[*]).

I don't suppose there's an easy way to run qemu where it just boots a
FreeBSD kernel...

[*] My FA-410 takes forever to autonegotiate, but once it does, it
works great.  All others work, including one that don't work
completely on any other open source OS...
