Perhaps gitweb should generate it's own ETag instead of messing with
'expires' header?

That'll be the winning solution. A combination of

 - cache SHA1-based requests forever
 - cache ref-based requests a longish time,  setting an ETag that
contains headname+SHA1
 - on 'revalidate', check the ETag vs the ref and only recompute if
things have changed

In the meantime, the code on kernel.org needs to be updated to the
latest gitweb. On our server, I'd say the newer gitweb is 3~4 times
faster serving the "expensive" summary pages. And much smarter in
terms of caching headers.
