I've not tried it, but v2.1.25 adds the file Documentation/serial-console.txt which gives instructions on how to use a serial console. The instructions say nothing about applying any patches, so I can only assume that it is now in Linus's kernel source.

I agree with Alan Cox's earlier post: screen is the correct tool for scroll back, not a more complicated console driver. The only case I am aware of that would really need another way is the issue of boot messages, and I think a serial console should cover that case pretty well.
If you have a server machine with a mono card then perhaps you should see about using syslogd to keep your error messages. Combined with a cron job for rotating the log files you can maintain a "scroll back" of an arbitrary period of time. You don't even need to modify the server processes; try something like: /usr/sbin/some_server 2>&1 | logger -t "some_server"
I missed the original post, so forgive me if I've missed something important. -- Paul H. Hargrove All material not otherwise attributed hargrove@sccm.stanford.edu is the opinion of the author or a typo.
