There's a plan but no code yet.  :)

linux-ide@vger.kernel.org is where this stuff gets discussed (though 
there's nothing on there recently about hotplug).

Can you share the plan with me (pdf, email archive, or web page)?  I've 
been tasked with adding hotplug support for the system I mention in my

a custom hack job or something more generic that could benefit more people.

Thanks,
Andy

<shrug>  Just "use SCSI infrastructure such as 
scsi_{add,remove}_device() to facilitate hotplug"
