I have Verizon FiOS as well. As luck would have it, you are not required to use the router as your router (though I agree that the router is serviceable). I have an ethernet cable coming directly out of the FiOS ONT to my FreeBSD-based router. I use the Verizon router on my LAN as a MoCA bridge for my TV's set top box. Seems to work perfectly fine, though Verizon claims that their router is required for optimal QoS (I use ALTQ instead).
