It works to the extent that the X server loads and
the fvwm2 window manager comes up with my normal
desktop. In fact, I'm typing this in a xterm at
that moment.
What I don't know is if the X server is ignoring the GPU.
It is unclear to me if the last "drmn0: Resetting chip
for hang on rcs0" is disabling some functionality. xwininfo
reports

which looks like what I expect for 'startx -- -depth 24'.
