I was aware of a bug like this in Mesa - which (IIRC) was recently fixed.

(The Quadro?  That's just the 'professional' version of the GeForce - right?)

Are you using Linux or Windoze?   If Linux, are you using the nVidia drivers
or the Utah-GLX drivers?   I'm not having any problems of this kind with the 
GeForce - and in fact the way we found the original Mesa bug was when I got
my GeForce cards and all the peculiar lighting problems 'went away'.

(BTW: The Quadro is a ripoff - it's an identical chip/board to the GeForce,
with the exception of a single resistor value.  If you know how to solder
small surface-mount parts, you can convert a GeForce card into a Quadro!)
