# Are you talking about RASTERCONSOLE? If so, note the following comment
# from the cgsix driver:
#
# /*
# * Unlike the bw2 and cg3 drivers, we do not need to provide an rconsole
# * interface, as the cg6 is fast enough.
# */
#
# So the cg6 driver apparently does not even use the raster console, even
# when it is enabled...
Apparently, theory != reality, here -- I notice a significant _loss_
of throughput on a sun4m cg6 when RASTERCONSOLE is enabled, believe it
or not.
I recompiled a kernel with RASTERCONSOLE taken out of the config, and
it now happily uses the on-board console driver (which I mistakenly
thought it didn't...silly me!) which _screams_.
