mdev is slow and missing features, it also requires that we load all the
modules that we include at once making the boot process slower.
udev is required for unl0kr (and buffyboard), it can also load modules
on demand (and asynchronously). Making the boot process considerably
faster on devices, especially for generic images where we have lots of
drivers for different display panels in the initramfs.
Additionally, import full fat modprobe from the kmod package, this is
required to support compressed modules.
This brings us more in line with other distros and generally improves
compatibility.
If devices use broken kernel modules which don't correctly define
modalias', these drivers may not be loaded by udev. This should be fixed
by defining the missing modalias statements in the driver.
This also runs udev earlier in the init, so that display drivers are
loaded before the splash in case they are needed.
