Great! I now recall that someone else had problems with hwclock
hanging the boot process. I don't fully understand why, because
for us the error messages just seem harmless and the boot
continues. 

I'll have a think about what the best way of solving this
is. Perhaps we should implement a dummy version of the rtc driver
just to keep it happy...

My guess is that this is just a /etc/syslog.conf issue, and
the messages aren't being sent to /dev/console

The whole console stuff is in the process of changing in the
unstable tree anyhow -- rather than implementing a tty, we're
going to implement a bidirectional console as a new serial
device. This should make life rather easier. Also, we're going to
present the console to domain 0 using a new event mechanism, so
there's no problem with people accidentally firewalling off other
domain's console as often happens at the moment.

They should be harmless. Again, I guess we could implement dummy
ttys, but this might cause more confusion.
