This allows the bfe driver to work properly on machines of all memory sizes, but it also caused machines with the mpt driver to trip the same check due to the overly large alignment mpt was asking for. So, if you see the message "bus_dmamem_alloc failed to align memory properly" start showing up on your console, please contact me ASAP so that we can find out whether busdma is failing you, or whether we have a driver that is asking busdma for an infeasible alignment.
