After some private answers and doing more testing myself, I've find out
that:
- On some IOS versions (10.6S and 11.S, for instance) it's possible to
enable CEF-switching and it reports as being enabled. But 'show int
switching' shows that packets never goes thru Autonomous/SSE switching path,
only thru fast switching path.
- Many people reported not being able to turn it on the versions they run.
- It also happens with ISL trunking.
- It isn't a problem on 12000 GSR.
Conclusion: if you do vlan-trunking but needs performance, go shopping for a
10000, 12000 or a Juniper... :)

Subject: [nsp] 802.1q and CEF-switching (7500)
Have anyone succeeded in running 802.1q on Fast/GigE interfaces of a 7500
router with dCEF ?
In all tests I have made with (a couple of 12.0S releases) it disables
Distributed and CEF-switching ("show cef interface g1/0/0.1") and keeps the
interface running on fast-switching.
