This path looks wrong - according to the aliases listing at https://www.mail-archive.com/misc@openbsd.org/msg164291.html the unit address of the k2-sata device which is a child of the k2-sata-root device should be 0, whereas above it is given as -1? Perhaps something in ofpathname is subtracting 1 from the unit address of 0 when it shouldn't. Does the following alternative work?
nvsetenv boot-device "/ht@0,f2000000/pci@5/k2-sata-root@c/@0/@0:2,\grub"
This sounds reasonable. I had no luck with the env value set by the installer as well and changed it to the alias hd:2,\grub manually. Think the regular boot device will be hd in most cases. You may get the alias list using the command devalias in Open Firmware. Don’t know if there is a way to get this list from a running Linux.
