It has - the 'image brightness' setting sets both gamma and 
brightness/contrast according to some fiendish Hamrickian scheme. I still 
preferred them as separate parameters, but that's the control to twiddle 
with - in practice it works well - to achieve a scan which does not clip 
either end of the histogram. You'll also want to set VS white point to 
0.01 and black to 0.0.

Like I said, aim for a rather pallid preview scan which exhibits neither 
full blacks nor whites. Use the levels shadow and highlight eyedroppers in 
PS to adjust to taste.
