No one, to my knowledge, makes the appropriate Gigabit Ethernet (ideally Dual Gigabit Ethernet) + Wifi Open-Source Hardware SBC that could be used as a router. There are a lot of SBCs with open-source software and mostly-accurate PDFs of their schematics, but very few (the Olimex OLinuXino project, maybe?) that are actually open hardware.
I do understand that truly open-source hardware is a tough sell, as Jay pointed out in his amazing piece "So you want to build an Embedded Linux system" [1]

And an EVK is likely built at a lower volume than a consumer SBC. The idea that someone can download your hardware design, modify it, and respin it for their desired open-source router but now with a piezo buzzer added might work for Arduino-scale hardware projects but simply isn't reasonable for something that reaches the performance required of a router.
I apologize I misread OP's question. I incorrectly interpreted it as "hardware that supports opensource firmware such as DD-WRT/Tomato".
In terms of hardware like you mentioned there's few open source SBC's at all. Even fairly open hardware like the raspberry pi have a proprietary firmware blob. I guess it will come down to how strictly you define "open source". If you define it as "we have firmware/schematics for every chip on the board" then we'll likely never have that (I don't think even Linksys has that type of access).
