ok, this patch was now in the mactel svn repository since about a month
and I've never ever seen a report about it failing. Also I asked on the
mailinglist for anyone having problems with that and got no answer,
execpt Joseph, the problem you have been seeing might have been that
one:

I would therefore hope it can be applied and thus appear in .20. I am
attaching the version that is now in mactel-svn (which also includes
geyser4 support).
