%changelog
* Sun Aug 29 2004 Paul Howarth <paul@city-fan.org>
- Add %%kernelsuffix to get smp etc. kernel RPM names right

* Wed Jun 23 2004 Paul Howarth <paul@city-fan.org>
- use specific architecture support provided by dkms >= 1.90

* Thu Jun 17 2004 Paul Howarth <paul@city-fan.org>
- better detection of the RPM for the running kernel
- can build modules for non-running but installed kernels, by specifying the
  kernel macro on the rpmbuild command line

* Mon Jun 07 2004 Paul Howarth <paul@city-fan.org>
- Initial RPM version.
