kernel-source or kernel-header?
As my video card is Radeon 9550.I need to rebuild the kernel in order to open 3D accleration.To build a module I need the kernel-source package. As my os is debian sarge,I upgrade it to debian unstable.But then ,I couldn't find the kernel-source package.some one told me "kernel-header might be suitable for you"
And I want to know why there isn't kernel-source package in unstable version? Is kernel-source in sarge equals to kernel-header in unstable?
