Hmmm. That's what got me, though - the laptop was sending an ARP reply, but it never got to the other end of the wireless link. I confirmed this by running a sniffer on the three hosts I involved in that test - the laptop (wireless node), the gateway (wired + wireless - bridging *somewhat* worked in ad-hoc mode, but I noticed some slowness), and the host on the other end of the gateway's wired link. In all cases, the laptop was able to find the remote host's MAC, but when it tried to respond to ARP requests itself, the gateway never received them.
