Where are the kernel headers?

[Toni Pizà]

I'm using a kernel 2.6.15-19 with KUbuntu Dapper Drake. Why the
linux-headers-2.6.15-19-386 package doesn't exist?

I have tried to install the 2.6.15-21-386, whose linux-headers package
is in the repositories, but during the boot process it is uncapable to
mount the root device (maybe because my laptop has a sata hdd).

Does anybody know what can I do to resolve my problems? Can I install
the linux-headers-2.6.15-19-383 package from the Debian Sid
repositories?

Thanks a lot in advance!
