There are 48 bugs in bugzilla which mention "noapic"

http://bugzilla.kernel.org/buglist.cgi?query_format=advanced&short_desc_type=allwordss...

And there are 173,000 on the internet ;)

We screwed this pooch a long time ago - years.  Perhaps if some of the many
noapic users could run a bisection search to work out when it broke we
could start fixing things.  But they all have a workaround so there's no
motivation.
