1) I guess the reason the shadow is black is we don't implement
GL_ARB_shadow_ambient. With the driver which can render the shadow correctly,
try to set this environment variable:

MESA_EXTENSION_OVERRIDE=-GL_ARB_shadow_ambient

to temporarily disable GL_ARB_shadow_ambient, and see if the shadow becomes
black.

2) I know of the wireframe issue, it's been bugging me since ever. It can be
seen e.g. in ETQW on the water and in Nexuiz with GLSL enabled. I think it only
shows up on R500.
