yes. most if not all.

Define "older" :) Even 2.2 kernels have worked this way for a while, so
it really depends on how far you want to go back. I think this policy
started in late 2.1.xx days IIRC.

Also, WRT older kernel compatibility, look at drivers/net/acenic.c or
the kcompat24 toolkit. These, and other code, illustrate how to be
compatible with older kernels without loading the source code down with
ifdefs. The basic idea is to provide a 2.4-like API on older kernels,
using macros and inline functions hidden in a compatibility header.
