Consider having /usr on a separate partition and /usr failing to mount
at bootup and times at system bootup, during which /usr is not yet
available, because it has not been mounted, yet.
These scenarios are the key scenarios to separate those parts of a
distros which need to be considered "essential" (have to go into /lib,
/bin, /sbin) and which to be consider "non-essential".

Rsp. this "other stuff currently in /usr" needs to move, too.

Really? The situation definitely has improved over times, but I recall
times, when not even "rpm" was able to run without /usr.
Consider taking out /usr from your fstab and to check how far you can get.
With /sbin/lspci you will be able to check your pci setup, with
/usr/sbin/lspci, you wouldn't.
Should setpci be used somewhere in bootup scripts, you likely won't be
able to boot up your system at all.
