No one is asking for a SEI CMM level type of model for kernel
development. A system of checks and development so that things
that used to work dont get broken is hardly too much to expect.

This isnt asking for too much isnt it ?

Is a bug database on drivers and kernel subsystems asking for
a SEI CMM level type model ?

i dont think so.
