I've noticed in several of the branches/heads (not too familiar with git terminology) there is an K26: IPV6 Mini build for 4mb routers. I was able to get it to build myself and I also modified the Makefile to include CIFS support rather then remove it. The resulting binary appears to be fine in terms of size. However given that I have no real idea what i'm doing in terms of embedded development and I don't have a jtag setup in case I mess something up I was curious if anyone has tested this build? The closest pre done build I was able to find was here: http://tomato.groov.pl/K26/build5x-042-EN/ but its only MIPSR2 and my WRT160N V1 needs MIPSR1.
