Yes, direct cabling the HDHR to a cheap PCI nic works great.

However, you do NOT need to have the backend serve DHCP to the HDHR.  Just
set the dedicated NIC to a static 169.254.x.x address with a 255.255.0.0
netmask (no gateway or dns).  The HDHR gets a link local address
(169.254.x.x) almost immediately after it boots.  Sure it pulls a different
address on every boot, but you should never configure the backend to
connect it by IP anyway, so it doesn't matter if it changes every time the
HDHR starts.

My /etc/network/interfaces file looks like this, no other config necessary
for the HDHR segment:

--------------------------------------------------
# primary NIC
auto eth0
iface eth0 inet static
   address 192.168.15.100
   gateway 192.168.15.1
   netmask 255.255.255.0

# HDHR
auto eth1
iface eth1 inet static
   address 169.254.15.100
   netmask 255.255.0.0
