Yes, the motivation was ultra bay hot swap. This works on DVD and CD 
drives. Hard drive installs work. However hard drive removal result in a 
hard kernel hang. The script gets to the beep successfully but then the 
hard hang. Unfortunately there are no log entries. (the latest kernel 
patches are installed)

Is there a way to debug this?

Thanks - Dan

Which is the more common mapping for hard drives in current  
distributions, hda or sda? I am trying to make ultra bay hot swap to  
work. Does it depend on an hda or sda mapping? Is it independent of hda  
versue sda?

I works way better (no DMA problems and such) with the libata, which
you see as sda. See
