this bypasses the convenient fact that there are 2 types of
unmaintained:

1) Drivers that barely, if at all, limp along and nobody has hw for
2) Drivers that no one person is the declared maintainer, but which do
get fixed when they break by "someone"

floppy.c is of the later kind; the hardware is widespread enough to make
that feasible I suppose; while the former kind are mostly ISA slot cards
that virtually nobody has (or only people who can't or don't want to
care about the linux kernel driver; a bunch of serial expander drivers
and a whole lot of the ISDN drivers falls in this category)

marking the category 1) drivers that limp along as "don't warn on
deprecated" is sort of fair; they're not far enough down deathrow yet
that they can be removed entirely, yet they also shouldn't clutter up
the build logs and they shouldn't prevent us from deprecating APIs that
are truely broken (*_sleep_on(), cli() etc) in 2.6 kernels...
