Multisampling buys very little, as the Nikon already sees pretty well into

Yes. I see no difference between 1x and 16x (I've only tested it with one
dark Provia slide, though), and leave it at 1x.

The worst issue with the 8000 is banding, which is sometimes visible in very
dark areas adjacent to very light areas.  You can eliminate it by switching
to a "superfine" scan, which uses only one CCD line instead of all three,
but the scan takes three times as long.

Actually, it only takes slightly longer: 4:30 vs. 3:40 for 645. Here are the
times I get:

Acquire thumbnails: 20 seconds
Acquire preview: 35 seconds
Minimal 4000dpi 645 scan: 1 min 30 seconds. (No ICE, 1x, not fine mode, 8
bits.)
ICE scan: 3:40
4x scan: 3:55
16x, 14-bit scan: 13:50
Super fine scan: 3:25
ICE, super-fine, 1x scan: 4:30
14-bit scan: 1:30
