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.
