Note that this post was made by Thomas De Schampheleire, not me. Yeah,
I know, two Thomas, it's confusing :)

No. In fact I'm not sure there is really a need for that.

Normally, if you use the modules_install target of the kernel Makefile
to install your own modules, it should call depmod automatically.

See
