Hmm, are you sure? man dmesg:
[...]
       -sbufsize
              use  a  buffer  of bufsize to query the kernel ring
              buffer.  This is 8196 by default (this matches  the
              default  kernel  syslog  buffer  size in 2.0.33 and
              2.1.103).  If you have set  the  kernel  buffer  to
              larger  than  the  default  then this option can be
              used to view the entire buffer.

So try dmesg -s 16384. That's good enough for me on a 4-way SMP
box with lots of SCSI on-board (and trust me, SMP generates a *huge*
amount of kernel logging).
