For kernel spew, you can also increase the kernel message buffer:
# Size of the kernel message buffer.  Should be N * pagesize.
options         MSGBUF_SIZE=40960

And for the VTYs, you can increase the scroll-back size:
options         SC_HISTORY_SIZE=200     # number of history buffer lines

Both these are kernel compile-time options.
