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).
