Can't, sorry. My goal is to get 3.18/3.19 working, but I really need
working kernel to debug userland (and then use that userland to debug kernel).

I was hoping someone has devtmpfs patches I could just apply over
2.6.28 and get a working system?

(Alternatively, I guess I should be able to do mknod manually. But
unfortunately ALSA does not want to work when I do that... and I
really need audio and modem support.)
