The is and lnc drivers both use bus-mastering DMA. I reckon these are the
cards of choice myself and apparently people are picking them up for
ridiculous prices in the US.

You want to look for PCnet or Lance based cards to use the lnc
driver. The is driver is going to be dropped probably after the
next release since it's now superceded by the lnc driver. Someone
in the NetBSD lists said they picked up a 32 bit PCI PCnet card
for $79! Apparently it needs PCI config support to be written into
the driver before it will work since the driver doesn't know the
irq pin etc.

If someone wants to send me one I'll happily get it to work. I've got the
docs next to me here :-)
