As far as I can see (just browsing the patched kernel sources) DMA is used. Looks like the ethernet chip (RealTek RTL-8139 or compatible) is connected to a PCI bus. There are very few DMM specific patches to the standard driver (drivers/net/8139too.c) as found in linux version 2.6.12 kernel sources.
