The information I was is that Gelato Pro *won't work* with a GeForce 
card, but vanilla Gelato will. This suggests to me that they designed it 
to work properly in that configuration.

Quadro cards are more geared to 2D optimisation than 3D. Not sure how 
that would help here...]

Oh I'm sure it works properly, but whether it works as quickly on a GeForce 
compared to a Quadro...

You mean this document:

http://www.nvidia.com/object/quadro_geforce.html

Just looks to me like there is more flexibility built into the card, which 
is exactly what you need when you're trying to off-load as much CPU work 
onto the GPU as possible... (for example being able to have all pixel shader 
IO in 32-bit per channel format looks useful from a general GPU programming 
point of view)

I was under the impression that in the GeForce 8 series they radically 
redesigned the whole GPU to make GPGPU much more flexible with less 
jumping through hoops. I'm not a super-expert in this direction though, 
so maybe Quadro does offer something particular that the GeForce 8 is 
lacking...
