Andrew,
I simply can't resist, don't take it personal.
All ATI display cards have 10bit LUTs.
If you don't believe it, here is a starting point,
with programs to test on a mac.

It's sad that no one really uses this technology,
even Apple doesn't. (Take a look at the dates when
Ben Singer found that out)
