A month back, there was discussion about hotswapping IDE disks.
I have a solution that seems to work, indirectly, using the SanMax
InClose PMD96-USB2 Mobile Dock.  This cage is physically compatable
with the PMD96i direct IDE cages, but has a translator from IDE
(LBA48!) to USB2, which I connect to a USB2 PCI card in my system.
With USB hotswap enabled,  the system seems to recognize when
disks are added and removed.  This allows me to do backups to
cheap big IDE hard drives, and swap them out for safekeeping. 
For more information, look at my web page in progress:

I am still working on this, so your mileage may vary.  I am
incompetent at software, so a more clueful person is welcome
to take over and do this right.  In any case, this provides a
functional solution for IDE hotswap without kernel patches, and
that might free up some wizard time for other needed tasks.
