64bit and 32bit DMA don't have anything to do with the CPU.
It's about the bus. 64bit DMA is only used for the PCI-E bus.
32bit DMA is correct for your machine and card.

Can you please give more kernel messages about this "Protocol Error"?

I don't think this cards supports the address extension bits.
(Which you actually need to get this working). But I can write
some patch that checks the hardware if it supports this or not.

I don't think that's strange. I would say such a nonsense is
common practice for vendors ;)
