Unlikely.

Anyway, there is GPIO7 connector on the board - try attaching it to the ground and turn device on. If this does not help - use this method for recovering:

For the record, shorting GPIO7 to ground on my Asus wl500g deluxe with board release "R1.33" zeroed the NVRAM OK: I powered off the unit, opened it up, connected a wire between the "GPIO7" and "GND" jumpers and powered it up: it started blinking the LEDs, then I powered it down, removed the wire and powered it back up: presto, NVRAM is zeroed out, and I again can access the device.

Also for the record, my original fuc^H^H^Hmistake was setting wrong vlan parameters on nvram: after nvram commit and reboot, the device came up ok but I could not access it on any address, neither via LAN nor via WiFi.

Oleg, your hint really saved the day: shorting the GPIO7 jumper is MUCH easier than soldering things on the board.
