i think the networking code is a special case - nothing else relies on the interaction of timers and IRQ contexts in such a deep way. (which it does for performance reasons.) I'd say 99% of all cli()/sti() users are in the 'introduce a per-driver or per-subsystem lock' league Linus mentioned.
I'm sure the serial drivers used to. Look at how they were using SERIAL_BH for example.
RMK's stuff fixes that so wrt. the current state of affairs you're probably right.
