(Thank you for reading between the lines and figuring out what was really wrong). I compile the module apart from the kernel, so kvm support was not enabled when compiling the kernel. In 2.6.24, the PREEMPT_NOTIFIER option is not user selectable in make config, but is selected for you when kvm support is selected. IMO, this makes building modules apart from kernel source unadvised; however, there seems to be no alternative with the pace of kvm development relative to the kernel release schedule.
