Why not?  They must or some equivalent to get these features.
I dislike this 2.6 "forward progress" that continually removes
features we have deemed necessary in previous kernel versions.

I don't understand the "what is it?" part of these questions.  As I
have continually pointed out over the years, we don't have "SMC" or
"SCC" drivers.  We have UART drivers that use SMCs or SCC, Ethernet
drivers that use SCCs or FECs, audio drivers that use SMCs or SCCs,
and so on.  It's a subtle but important configuration selection.  You
select the feature you want (uart, Ethernet, audio, ATM, etc.), then
you can be further prompted for peripheral routing information if 
necessary.
We have discussed this at length in the past.

Thanks.
