After recently having a conversation on alsa-devel about it, it was decided it seems to be a PCI issue. The "devices" in question....

Correct. The card has not worked at any point for me in Linux.

I just compiled this but I'm a bit unfamiliar, sorry :( It is giving me
"mmap error". Is this the what you are looking for?
./mem -N -m -s 0xf4000000
