I have these distributions running on 2 WRT54GLs.
Say Kamikaze is on Device 1 and Whiterussian is on Device 2.
This is what I'm proposing:
Device 2 will be assigned a Local IP address of 192.168.2.1
Device 1 will stay with 192.168.1.1
Disable DHCP server on Device 2.
Disable br0 on device Device 1.
Interconnect Device 1 to Device 2, Lan port to Lan port.

Would DHCP server on Device 1 issue 192.168.2.X IPs to clients connected to Device 2?
Would WiFi on Device 1 remain operational with br0 disabled?

I'd give it a go but I'm a newbie and don't know how to disable the bridge on Device 1 (i.e. br0).
Can someone help? Thanks in advance.

Found some useful info at the following: http://home.x-pec.com/~ivc/sites/ivc/wrt54g/

The above commands seem to be somewhat antiquated.
Looks like Kamikaze supports the admcfg and vconfig commands as demonstrated in: https://forum.openwrt.org/viewtopic.php?id=30
