I mean all I really want for Christmas is a 64-bit v7 with TCP/IP support, a screen

The third one is a solved problem. The second one would not be that hard to adapt, say,
uIP 0.9, to v7. That first one would require some work with C type sizes, but getting
larger is easier than the reverse. It's that last one.
Having said that...maybe what I really want is 64-bit 4.3 BSD?
I mean, just a Unix, without all the cruft of a modern Linux, but which can actually take
advantage of the resources of a modern machine. I don't care about a desktop, or
even a graphical environment, I don't care about all the strange syscalls that are
there to support particular databases, I don't care much about being a virtualization
host.
I think xv6 does SMP? (param.h says NCPU = 8, at least).
You’d need to add a network stack and a userland, but there are options for those …
