I think so, though I admit I don't remember using this personally since
the introduction of e820 RAM mapping support.
Dmesg will show if the memory is limited. For the swiotlb to effectively
disable no RAM > 0x100000000 may be used.

But this test isn't IMHO terribly important at this point - the driver
makes invalid use of the DMA API and it has to change. The test could
only explain _how_ exactly does it fail, we already know _why_ it does.
