Question about OOM-Killer

I'm chasing down a system problem where the DMA memory (x86-64, god knows why it is using DMA memory) drops below the minimum, and the OOM-Killer is fired off.

It just strikes me odd that the OOM-Killer would be called at all for DMA memory. What's the chance of regaining DMA memory by killing user land processes?

I'll admit, I know very little about linux VM, so perhaps I'm missing how oom killing can be helpful here.
