UnBlock-US are also doing the same thing and have a long list. They however have stated the following:
Unblock-Us: We have been working very hard to try to come up with solutions for as many different routers as we can, however, it has now become impossible for us to continue trying to fix every single router make and model and firmware version, as this is now taking us away from the day to day issues that we have to address to keep bringing the best possible service we can to you, our subscribers.It is for this reason we have had to make the difficult decision to stop trying to create fixes for routers other than the ones that are listed below.
