theres a few things you can do. first, probably the simplest thing would be to dump all the output of the kernel make to a file.
ie: make > whateverfilename
where whateverfilename is whatever you want the dump of the kernal to be called. this way, you can
cat the file to dump its contents on screen.
second, go to
freshmeat.net and search for a video capture program. find one that will capture screen output and that will let you set the focus to an x window. while running X ( which the video capture program will require ) set the focus to the console sessions where you will be cat'ing the output of the file you created earlier.
