Good to hear.

This i was only to get the patch to apply, because the context had
changed slightly (because of the definitions for the s2 cards), right?
No changes needed to the applied code? I tried this with a multiproto
tree also, and it works fine (but patch from one does not apply to the
other)

I think it is necessary.

This line is, to the best of what I can see not added by my patch,
neither in my version, or the version you provided for the multiproto
tree. If it is in fact part of my code I'd appreciate if you posted the
line in question, or the equivalent warning from an otherwise unchanged
hg master clone.
