which kernel headers package to use?

[Andres Salomon <dilinger@voxel.net>]

I have a package (keepalived) that needs to depend upon 2.4.2[34] kernel
headers.  I assumed kernel-headers-2.4.24-1 would be ok, but it appears to
only exist for alpha and i386.  What's the recommended kernel-headers
package to use?  I can't use the linux-kernel-headers package, as it
doesn't include net/ip_vs.h.  Will the kernel-headers-2.4.24-1 package
appear for other archs?
