\setupfootnotes[n=2,columndistance=3em]

\starttext

\dorecurse
  {100}
  {Does it work or not. \footnote{Let's see how this works,
   well it does not work although it should and did one day

\stoptext

It looks like I intermixed a \box and \unvbox as well as does not set the
split hsize. So, here is the patch that should go into core-not.tex:

\unprotect
