Using the same logic as the other framebuffer fixes committed in 2.6.11,
this is a set of fixes to make TCX functional on the console again. Adds
the tcx_pan_display function, sets the
all->info.var.{red,green,blue}.length values to 8, and runs fb_set_cmap.
Also looks for the correct SUNW,tcx prom value.
This patch just slipped through the cracks.
