interesting, took me a while to identify the problem (has to do with empty 
parameter). I'll send you a new syst-gen.tex to test.

now, to the hanging: one complication is that once a font is 'defined', its 
characteristics are kind of fixed; i could remove this limitation but it 
would not help at all, since hanging get fixed in tex itself. this means 
that for the preloaded cmr fonts, (or any preloaded font) one has to 
redefine them; also, because of the design sizes, cmr's are not mapped onto 
Serif, so here we need to manually set the fonts (unless one defines them 
as any ps collection, ignoreing the design size)

% output=pdftex

\setupfontsynonym[cmr10][handling=pure]
\setupfontsynonym[Serif][handling=pure]
\setupfonthandling[normal][left=1,right=1]

% so here we load 'm again

\usetypescript[cmr] \setupbodyfont[10pt]

% handy for tracing the hanging

\showframe

% off we go

\starttext
   \dorecurse{100}{testtest, }
   \setupalign[hanging]
   \dorecurse{100}{testtest, }
   \setupbodyfont[pos,10pt]
   \dorecurse{100}{testtest, }
\stoptext
