Maybe try a different brand of motherboard: Lots of Linux-folk have in the past noticed that multiple PCI bus-masters sometimes corrupt each other, even though they shouldn't. It seems to be a motherboard/brand issue of some sort, or maybe a chipset issue.
The eepro100 is a bus-master, as is the Ultra33.
Previous DMA problems have been reported with Adaptec SCSI adapters interacting with soundcard-DMA and/or network-card DMA.
Sounds like maybe something similar here..
PC hardware is just plain cheap, and often not tested in workstation scenarios. But now that DMA is becoming commonplace in peripherals, things ought to be improving.
