I looked at the drivers/sunbw2/bw2_driver.c code, and it seems to probe

use it.  I definitely don't want it to be able to read anything but the
framebuffer hardware through the channels of the proper driver.

I'm not sure what needs xrender for decent performance.  I haven't
missed it up until now.  :-)
