I am not sure I understand your question. drm-fbsd12.0-kmod is a port so 
it's built from /usr/local/poudriere/ports whereas 
FreeBSD-kernel-venus-12.1_3 is one of base packages build from /usr/src.

If you are asking if /usr/src is the same when building ports and kernel 
then again, no, because when building ports the jail's /usr/src is used, 
whereas when building the kernel the host's /usr/src is used.

But I verified that both are the same, i.e.,

diff -r /usr/src /usr/local/poudriere/jails/12rel1/usr/src

doesn't return any differences, apart from the additional kernel 
configuration. They are both 12.1-RELEASE-p3 (checked the version 
against sources in Github and SVN).

I can certainly build and install a stable kernel, but I believe I would 
also need to recompile the packages with stable /usr/src in the 
poudriere's jail, which means creating a new jail and possibly 
recompiling all the packages? Can I install stable kernel into 
12.1-RELEASE-p3 world?
