Is there a way to find a device's IP address
with it's mac address. You would think that
there would be some sort of switch for ping
that would allow this, but of course there is
not.

Use a tool like superscan to ping every IP in your local subnet.
Then use arp -a to view the arp cache. You will be able to see IP addresses and their corresponding MAC.

If you want to do this outside your local subnet, it's tough luck I'm afraid. Due to the way IP routing works, it is not possible to find this information.

Assuming it's internal...
Check your DHCP... that'll tell you what MAC goes to what IP.

magic packet from AMD. This is normally a LAN remote power on tool but has the discovery tool for IP to MAC address.

To find magic packet on the AMD web site takes a little digging but its there.
