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.
