The last thing I want is to have another PCI slot sucked up by a card doing something that should have been implemented on the motherboard. It sounds like the board can be relatively easily patched, which is what I'll be doing on my A1. I hope the details surface soon.
Upon rereading though...
It seems UDMA and Ethernet cannot be used simultaneously.
What about plain DMA and Ethernet? If they work together, that's good enough for me.
