Starting with Solaris 9 the old SunLogo.pm was renamed SolarisLogo.pm, but we failed to update CAM for this change. With Solaris 10 it's called SolarisLogo.old. So if you want that old backdrop back (embossed "old" Solaris logo in Sun Blue) just:
ln -s SolarisLogo.pm SunLogo.pm
or for S10:
ln -s SolarisLogo.old SunLogo.pm
Or symlink whatever pixmap you want to SunLogo.pm. Although it is much better not to have backdrops at all, which is why I've never opened a bug against this issue.
