I'm sure this problem has been resolved long ago but I can't remember.
It may be the check for whether an entry is a multi-mount or not that is
at fault but I have no idea what patches are included in SLES10.

This pre-analysis is really something that the downstream package
maintainer needs to do so that I can hopefully make some sense of what
may or may not be included in the package already.

You might check to see if
http://www.kernel.org/pub/linux/daemons/autofs/v4/autofs-4.1.4-multi-parse-fix.patch
has been applied.
