I was wishing the kernel would offer some minimal support for
network, sound and full screen video for my hw :(.
But it seems I need to load modules to achieve this. And to load modules,
 it needs some kind of "hotplug" called udev or mdev.

No manual modprobe, I need hotplug. Why have udev then,
 if we have to manually modprobe ?
Yes I think reading /sys will be the job, but why the user has to do
such things and not the kernel ? (get crazy and put udev
and all the hotplug stuff inside the kernel.)

yes still learning, testing and will never stop.
