(And this is pulling a potential solution out of my butt... 8-)

If you're talking about NetBSD clients, or other clients that use
NFSv3, you might try using NFSv2 (by specifying the -2 mount option).

It could very well be that there's no NFSv3-specific problem, but
that's where I'd put my money.  8-)
