I just scanned some kodachromes on my old leafscan45. Since I never
thought there should be a specific kodachrome issue, I thought I would
take a look once again at some previous scans and the trannies 

there seems to be absolutely no kodachrome issue. My experience with
this scanner is that what the eye sees on the lightbox is what the
scanner sees. I wonder whether there infra red or UV issues that people
are experiencing. 

If anything, the kodachromes contain fewer abberant over saturated grain
particles in the deep shadows and thus tend to look pretty natural. 

as far as shadow detail is concerned - I can scan a processed unexposed
piece of transparency film and see clearly through the dmax with out
ajusting the exposure time above normal (which can be extended to 2+
stops over normal).

on an average wide range transparency on a 16 bit 'raw' unprofiled scan
the the average range of the histogram is about 1/3 of the width of the
16 bit range. I have never ever scanned anything which came even close
to filling the entire range.

that is not to say that it produces the ultimate in quality but I think
we have passed a threshold beyond which 99.5% of the time in a
commercial repro environment, the quality is acceptable. 

good drum scans can give crisper grain detail and scan some film sizes
to much higher rez 

productivity is definitely not the name of the game with this scanner
which is probably why it was discontinued
