No--- there was some framework done for this, but it depended on kerneld
and so was rendered useless when kerneld died.

(And good riddance, too; it was an extremely cumbersome method, with the
driver sending messages to kerneld to record keyed information into a
database or query the database by key... So it had the same purpose as
the module parameters mechanism, just with outcalls for keeping the
settings, and it required some kernel code changes to support it, which
are (IMO) superflous...)
