Ok, well, I though it would be due to some upstream changes but it's
possible that I either mis-read those changes or they got themselves
changed in some subtle way after I did that commit :-)

I still find it fascinating that it doesn't break for me here since it
is effectively the same machine model !

I'll do a patch fixing that but it will have to wait for monday.

Cheers,
Ben.
