useful if you could allow kernel modules to be bound to a particular

and/or complain if the kernel is upgraded. This should prevent
unnecessary kernel panics when you upgrade. The Linux kernel has been
doing this for years.
The FreeBSD DDI/DKI is not well enough documented, let alone versioned, let alone stable enough over time for this to work.
Consider how long a third party binary-only driver would keep working for someone following -current, and you will see the problem.
I think for current all bets are off anyway. I think supporting a 3rd party
driver should really only "have-to" support releases. Now I may have to re-evaluate
that thought for a stable tree as there is a level of confidence there that everything
else will probably still work... it could be tricky :)
