my SCC serial driver - this one works less well in 2.6 than it did in 2.4,
most likely due to the way flip buffer push is handled now - i.e. no
immediate push of received characters to the line disc. if the handler
runs in interrupt context, and the bottom half for pushing is run as
delayed task. 9 out of 10 ping packets end up in the bit bucket this way.
I haven't figured out how to prevent overruns yet, and getting this right
will require a bit more testing.
Anyway, the basics are working, and maybe someone can figure out a better
way to push characters up to the ldisc.

SCC_clocks is unused. Is this intentional?

when I'm talking to journalists I just say "programmer" or something like that.
