The kernel already saves the *visible* screen when switching VC's, the
buffer (AFAIK) is visible rows*visible columns in size. Somebody who
wants this feature (not me, if I want large scrollback I use xterm) could
increase the buffer size. As for files, add /proc/vcs/... to access the
entire buffer, probably root only access.
