Thanks Hans! Works nicely (as always).

Just as minor comment in case someone faces the same problem:

There's already a

\def\strc_formulas_handle_sub_numbering

in cont-new.mkiv (line 36; ConTeXt ver: 2012.08.16 22:20 MKIV fmt: 2012.8.21). 
So to make this fix work I had to redefine / replace the original command 
instead of just putting it there.

Cheers,
Andreas

You can put this in cont-new.mkiv (after \unprotect):

\def\strc_formulas_handle_sub_numbering

 Dear all,
 
 I am having problems with subformulas.
 
 The following example does not display a subnumber (i.e. I get (1) and (2) 
 instead of (1a) and (1b)):
 
 % start example 
 \starttext
 % from 
 % does not display subformula numbers
 \placesubformula
 \startformula \startalign
 \NC a_1 x + b_1 y \NC = c_1 \NR[+][a]
 \NC a_2 x + b_2 y \NC = c_2 \NR[+][b]
 \stopalign \stopformula
 % stop example %
 
 This example is taken from http://dl.contextgarden.net/myway/mathalign.pdf 
 page 6 
 
 I am not quite sure for how long this is not working. I have been using the 
 following alternative, which used to work but now gives me an error with the 
 latest beta (ConTeXt ver: 2012.08.16 22:20 MKIV fmt: 2012.8.18):
 
 % start example 
 % the following used to work in an earlier version
 \startsubformulas[eq:ax=b]
 \placeformula
 \startformula \startalign
 \NC a_1 x + b_1 y \NC = c_1 \NR[+][a]
 \NC a_2 x + b_2 y \NC = c_2 \NR[+][b]
 \stopalign \stopformula
 \stoptext
 % stop example %
 
 Any suggestions?
 
 Cheers,
 Andreas
