    i386 exhausts lowmem very quickly. SCSI is in a bit better shape than
    network devices as the multiplier is only around 4 compared to 16 for network
    devices.

    My point stands, though. Forcing every new feature to go in via sysfs is
    not the right thing to do. Some people don't/can't use it, please remember
    them.
