I think that homebrew devs running Linux will only have access to a dual core 3.2 GHz processor, which is nothing to scoff at, but i doubt we can get last gen emulation.
If psp can emulate n64 and ps1 with only a 333 MHz processor, i would say within a year we have a dreamcast emulator. Also, i dont even know if anything has to be coded from the ground up, as it runs linux. I dont know if there is a project 64 for linux, but if there is it should run on launch day...
