Correct. The already built module works perfectly on the updated kernel.

Not that I know of. There is a volatile directory where restricted
modules are placed (afaik) but no other special directories exist. I
also don't think it will work...

The kernel, for instance, provides a tg3 driver for Broadcom NICs. The
Precision 390's, however, require a more recent tg3 module, which DKMS
provides. But DKMS should overwrite the kernel provided tg3 module,
replacing it with the updated one. If placed in an
non-updated /lib/modules/... directory the updated tg3 module would
indeed remain there, but the kernel update would install the original
tg3 module at the original location, leaving us with two tg3
modules... :(
