The destroy_dev calls for aliases have been removed in -current on 9th Dec
2002 (one day after I sent the email). See PR kern/36413. The fix hasn't
been MFCed but there's no need - the code is wrapped in '#if
(__FreeBSD_version >= 500000)'. The fix for BKTR_USE_FREEBSD_SMBUS hasn't
been commited.

I didn't send-pr but will recheck the status of things over the weekend
and perhaps will do.

To other readers: in my original email
(http://docs.freebsd.org/cgi/getmsg.cgi?fetch=2276+0+archive/2002/freebsd-current/20021215.freebsd-current)
I talked about another problem (limits on the maximum number of devices).
When I reread what I wrote at the time I have to say 'sorry for my
English' :-).
