You don't imagine what's in my config, Nikita. :)

For the sake of full disclosure: my AP is an off-the-shelf Netgear 
DG834G, equipped with a DGTeam firmware which is only marginally 
different from the original Netgear one. I have enabled and configured 
wireless as an AP, and disabled anything else (NAT, DHCP...). The 
DSL/WAN side is unused, and the Netgear basically behaves like a hub 
between its LAN and WLAN sides. This is enough for dnsmasq to work(with 
static MAC-based leases, so the MACs do travel properly through the AP).
