Free Bsd device namings

I haven't used Free BSD for years.
Could anyone tell me if following device namings
are still used on the latest Free BSD (pls
apply correction when applicable) ->

/dev/ad0->1st hard drive on IDE1
/dev/ad0a->1st partition of 1st hard drive on iDE1
/dev/ad0b->2nd partition of 1st hard drive on IDE1
/dev/ad1->1st hard drive on IDE2
/dev/ad1a->1st partition of 1st hard drive on IDE2
/dev/ad1b->2ndst partition of 1st hard drive on IDE2
/dev/rfd0 ->floppy drive
/dev/cd0a -> cdrom
COM1(/dev/sio0); com2(/dev/sio1); com3(/dev/sio2)

on 5.1 (which I'm using) (this is from memory. . i'm not at my machine right now..)

/dev/ad0->1st hard drive on IDE1
/dev/ad0s1->1st partition of 1st hard drive on iDE1
/dev/ad0s2->2nd partition of 1st hard drive on IDE1
/dev/ad1->1st hard drive on IDE2
/dev/ad1s1->1st partition of 1st hard drive on IDE2
/dev/ad1s2->2ndst partition of 1st hard drive on IDE2
?????? ->floppy drive
