It was just me forgetting to hit reply all.

Yes, this is an issue. In general gpio numbers can be even more than
hundred.  So, Joerg, is there any bad side effect if this value is
increased?

It is not included. The main reason is there is no good documentation
written. See a discussion about this a couple of weeks ago in this
list. I have volunteered to do this, but I'm really busy with work
until the end of this week. I'll try to do is beginning of next week.
Of coure, if you'd like to help you're more than welcome.
