Yes.  Any new device gets added here automatically.

Good to hear.

Is the device an add on PCI card?  If so it is possible that there is
some resource conflict and the OS simply does not see the card.  To
check to see if the card is visible, have a look at lspci.  You do not
need any flags.  If the device is not listed, try moving the card to a
different slot.

If it is listed, check to see if the driver is loaded:
lsmod |grep tulip

If you do not get anything back, try manually inserting the module:
modprobe tulip

Have a look at the output from dmesg to see if there were any problems.
 Does the interface now show up in "ip addr"?

The package is called dhcp3-client.  I use it because I am very familiar
with it's configuration.  I almost always want to override or modify the
DHCP assigned variables such as DNS servers, default domain name search etc.
