kernel devel provides obsoletes

[Elan Ruusamäe]

why *-module-build conflicts with other *-module-build but doesn't obsolete each other?

my suggestion is to add to kernel.spec:
%package headers
Provides:   kernel-headers = %{epoch}:%{version}-%{release}
Obsoletes:	kernel-headers

%package module-build
Provides:   kernel-module-build = %{epoch}:%{version}-%{release}
Obsoletes:	kernel-module-build

$ rpm -qa|grep kernel
kernel-headers-2.6.16.20-1
kernel-module-build-2.6.16.20-1

$ poldek --sn ac -u kernel-grsecurity-{module-build,headers}
