When handling FBIOPUTCMAP_SPARC, sbusfb fails to initialize cmap.transp,
which quickly leads to an oops when fb_set_cmap() dereferences it.

First encountered in Aurora Wombat kernels and seems to afflict mainline
as well. Patch is against 2.6.7-rc2. xorg still fails to actually get
anything to display on my CG6, but at least it no longer oopses the kernel.
