with 'don't use genkernel' I meant 'don't use an initrd' - because it adds a 
lot of time to the boot. And with everything essential in the kernel it is a 
useless waste of time. But even if you don't use genkernel to create an initrd 
- there is no reason to use it at all. With debianutils installed make all 
modules_install install is all that is needed to compile a kernel, install the 
modules, copy it to /boot and create vmlinuz and vmlinuz, System.map and 
config sysmlinks.
