Using mesa and nouveau from git as of today (commits cd7d71f1 and 6dd8ad4e
resp.), it manages a little better, but still doesn't start up correctly.

When starting manually, it initialises the screen which what looks like the
familiar stipple pattern, except that there are about 100 almost horizontal
black lines across the it. They're a single pixel high, and run for about 128
pixels along before dropping down by one pixel. And then it locks up, eating
CPU in nouveau_dma_wait():

0x0000000002234c2c in nouveau_dma_wait (
    userchan=0x263ab70, size=13) at nouveau_dma.c:99
99                                                      get = READ_GET(chan);
Missing separate debuginfos, use: debuginfo-install xorg-x11-server.x86_64
