It looks like this one does have Adam Baker's sign-off (and it is sad
how long this patch seems to have sat without being submitted to
mainline).

I don't know who originally had the idea of removing that code.  See
[1], [2], [3], and [4] for some early discussions.

The current "intel parport bug" test this patch removes seems to have
been introduced between 2.3.10pre5 and 2.3.10 (thanks to Dave Jones
for the git tree that makes such searches easy!).  That means some
time around June or July, 1999.  At the time, the parport maintainers
according to MAINTAINERS were Phil Blundell, Tim Waugh, David
Campbell, and Andrea Arcangeli.  From the patch "[PATCH] parport is an
orphan", 2007-03-05, I infer that not all of them are still interested
in the driver and whoever _is_ interested is probably subscribed to
the (low-volume) linux-parport list.

I'd say, why not get this patch in linux-next or -mm somehow and see
if anyone screams?  It would be _very_ useful to find an actual
instance of the "intel parport bug" so we could see what that code was
supposed to do and do it better.

Thanks,
Jonathan
