[SPARC]: TCX Framebuffer fixes
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. Originally by: Georg Chini <georg.chini@triaton-webhosting.com> Signed-off-by: Tom 'spot' Callaway <tcallawa@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
