Updating /ofwboot did not help in any visible way.

Latest experiment:

Rebooting with command: boot netbsd.u8
Boot device: /sbus/SUNW,fas@e,8800000/sd@0,0  File and args: netbsd.u8

Failed to load 'netbsd.u8'.

Boot:


Updating sources today and I can (still) boot a completely rebuilt
GENERIC kernel, but a kernel built of GENERIC minus the floppy disk
