"Debian's kernel source packages are named linux-source-[version]. The current official source package versions are linux-source-2.6.18 (stable), linux-source-2.6.21 (testing and unstable), and linux-source-2.6.22 (unstable and experimental).
"Binary Debian kernel packages are named linux-image-[version]. It's been this way since version 2.6.12, if you're remembering the olden days of the kernel-source and kernel-image packages. The new naming convention opens the door to using other kernels with Debian, which I don't know what those would be, but Debian is ready for them."
