My guess is "sometimes" in the above comment means "On sun4c/d/m".

If you wanted to test in 2.2.x without the aforementioned patch, you 
might be able to do something like (specific to your sun4m):

if (sdev->irqs[0] == 0) {
	sdev->irqs[0] = 0x35;
	printk("qpti%d: Adapter reports no interrupt, "
		"blindly assigning irq 0x35\n");
}

...and see how the rest of the driver likes your card.  This is just off 
the top of my head-- no guarantees, of course.
