Thanks for the link. (I am embarassed to admit that I actually had read the linked page a while ago but had completely forgotten about it.) But I need to build a profile based on the color rendering of the Coolscan lightsource/sensor combo.
Relatedly, if I get a Kodachrome Q-60 traget slide and scan it, is there software that will generate an ACR profile from that (AFAIK, the Adobe profile generator only supports the Macbeth/Xrite 24 target as a target).
