I use screen most of the time in my terminal sessions, which also
includes a nice option for scrollback.  Putting the following in my
~/.screenrc file works like a charm:

        defscrollback 10000

This is IMHO a bit more preferable than using syscons scrollback,
because syscons allocates memory inside the kernel for the scrollback
buffer IIRC.  I tend to prefer userspace allocations when possible, like
the xterm -sl or screen's scrollback.
