$ssbump is a material parameter that flags a $bumpmap as being self-shadowing. It is only supported with LightmappedGeneric and requires the Orange Box.
You can read more about the technology behind it in this paper.
Tip:Self-shadowed normal mapping is actually faster than the standard method!Example
LightmappedGeneric
{
$basetexture nature/rockwall_cave02a
$surfaceprop concrete
$bumpmap nature/rockwall_cave_02a_height-ssbump
$ssbump 1
}
Creating self-shadowing bump maps
Valve's tools for creating ssbumps aren't in the SDK yet, but there is a way to create them manually.
