The attributes only works for characters, not macros.

\usetypescript[cambria]
\setupbodyfont[cambria]
\appendtoks
   \setmathattribute{regular}{tf}
\to \everymathematics
\starttext
$ABC αβγδεφ ΦΨ$
\stoptext

The names \alpha \beta etc are currently hardcoded in char-def. The only 
way to change them is to move mathname="alpha" from 0x1D6FC to 0x03B1. Or 
use \greekalpha, \greekbeta etc (essentially taking the text glyphs).

Hans, we need to think of mechanism to switch between upright and italic 
greek letters for the macros.
