Must...have...interrupts.

You are 100% correct.

That said... I'm tempted to extend NAPI just a bit, to provide an "always poll" mode. It seems like all the bug reports I get these days for 8139too are caused by x86 ACPI/APIC/irq routing troubles completely unrelated to the driver. Tulip-almost-NAPI in 2.4 has an always-poll mode, so I have a convenient excuse :)
