Ok, my knowledge on this is a little fuzzy, so my technical explanation of the problem may not be 100% accurate, but it does convey what you're running into.
When you bridge a client/station interface, there is a problem with the number of available mac addresses in a frame, which causes the response packets to not be routed properly when you ping like this. The ways I've solved this exact situation: 1. I setup AP1 in your case as a separate subnet: 192.168.3.xxx, then use routing rules. This works well enough, with the exception of device discovery. I had my PS3 hooked up wired to AP2, and it could not detect a media server on AP1 due to broadcasts not being on the same subnet. 2. I hacked up the arpnat patch from the Gargoyle Router project to allow bridged client mode (what you're doing now). This allowed me to run 1 big subnet, but it screwed up ipv6 discovery for devices beyond AP1 (dhcp/radvd server was on the other side of AP2). I only have this patch working through 2.6.32 at this point, not tried anything more recent. The router it runs on is ar71xx based, and openwrt defaults to 2.6.32 for this device.
