I've put them in http://members.optusnet.com.au/callumgibson/verboseboot.out
for you. This is a boot (and shutdown) of the kernel which exhibits the problem
(hence kernel.old in output).

(On the plus side, this HP laptop now suspends and resumes properly after
5 years.  Not sure when that started happening.)
