  It doesn't "remain unlit". It's just that the angle of incidence of the
light on the surface is so small that the diffuse illumination is very dim.
  This would also happen in real life if you had a room with walls and floor
which don't reflect light (but which you can somehow see anyways).
  The reason why the ceiling is illuminated as well is because light reflects
from the floor and walls and illuminates the ceiling.

: even when I turn on radiosity.

  That's just a matter of tuning the parameters. You may want to pump up
the diffuse component of the room and/or the brightness of the radiosity.
