Hans,

This file will produce the problem:
\enableregime[mac]
\mainlanguage[en]

\usetypescript[lmodern][\defaultencoding]
\starttypescript[serif][default][size]
  \definebodyfont[9.5pt,10.5pt][rm][default]
  \definebodyfont[9.5pt,10.5pt][mm][default]
\stoptypescript

\setupbodyfont[lmodern,rm,10.5pt]

\usemodule[ancientgreek][font=GreekDioxipe,scale=2.15,altfont=GreekCanonica,altscale=0.9]

\setupfootnotes[conversion=numbers,way=bytext,location=page,rule=on,bodyfont=9.5pt,style=normal]
\starttext
This Greek should be scaled at 2.15 its design size
\localgreek{>'alfa ka`i b~hta}

This is more sample text.%
\footnote{This is a sample footnote}
\stoptext

Thomas, Luigi—
Thanks for tips: they are much appreciated.
As it turns out, I had already reinstalled ConTeXt 2008.11.10 21:40 using TimeMachine.
What is distressing is that the problem remains. I can either set an article with LM and Greek without proper scaling for the Greek or set the article with LM and proper Greek  but without the footnotes (arithmetic overflow).
In the first case, I have
\usetypescript[lmodern][\defaultencoding]
\starttypescript[serif][default][size]
 \definebodyfont[9.5pt,10.5pt][rm][default]
 \definebodyfont[9.5pt,10.5pt][mm][default]
\stoptypescript
and in the second
\definebodyfont[9.5pt,10.5pt][rm][default]
\definebodyfont[9.5pt,10.5pt][mm][default]
There is no problem with other text fonts, by the way.

in order to solve this (not sure what the problem is) we need small test files (since i never use greek i have no clue otherwise)
