	If you can compile a kernel, you can set the flags on the
	esp device:

## The following flags may be set for the NCR53c94 based esp driver:
##      bits 0-7:  disable disconnect/reselect for the corresponding target
##      bits 8-15: disable synchronous negotiation for target [bit-8]

	To disable sync for all targets, you should be able to use:

esp0    at sbus0 slot ? offset ? flags 0xff00           # sun4c

	Though please submit a PR on this - it would obviously be better
	if NetBSD could handle it automatically. If you would be willing to
	ship the drive to someone to work with, its probably worth mentioning
	:)
