I think this is your problem -- the OpenBSD partition needs to be a
primary partition (hda1-hda4 in Linux terminology, or (hd0,1) -
(hd0,3) in GRUB language, and you have it as an extended partition
(hdb6).  This is not supported.  Reallocated your fdisk partitions so
the OpenBSD partition is a primary partition and reinstall (you may
have to resize your extended partition, ID=5, to make room).
