Open Wireless on an office LAN

On an office LAN with all domain workstations and a single domain controller.  None of the workstations have wireless cards.  There is no wireless traffic on the LAN.

The LAN is protected by a hardware firewall connection to the internet.

How insecure is it to add a linksys wireless (WRT54G) router on the inside, for the office waiting room?  An OPEN (unencrypted) wireless for use by visitors only, for their personal web surfing while waiting.

Would such a visitor (or a wireless user in an adjacent office) be able to see LAN packets, even though all LAN users are wired-connection-only?  Is such a system hackable from the wireless, even though the workstations are on a domain and the wireless users won't be domain users?

Like this:

Internet --- Firewall --- LanSwitch --- Domain Controller
                                                      |----Domain Workstations
                                                      |----Linksys Wireless Router

Thanks for your thoughts on this.
