No one stepped up to test patches for it either when I last posted patches to
convert it from timeout(9) to callout(9).  I have a few more drivers that are
both very old and that people have no business using in 12 (think ISA
adapters that don't do DMA and can't be used with pccard) that I will be
removing over the next little while.  I brought up a list of drivers on arch@
a couple of years ago and the conversation drifted off into the weeds about
trimming GENERIC, etc.  No one objected to the specific drivers I listed
though (and I got a few pleas of "please remove").  If someone shows up
desperately clutching an ISA adapter they can always dig up the source from
svn and deal with forward porting it for whatever API changes have happened
since it was removed.
