For the purposes of the test we should be able to limit to 4G, without any big loss in coverage. v2: - No need to try again without the modparam; if it's not supported it will still load the driver just fine. v3(Petri): - Add a helpful debug print in case the kernel is missing support for the lmem_size modparam.
