David,

now hot-swap may not be supported on all interface types, that may be what you have run into, but with SCSI or SATA you should be able to hot-swap with the right controller.

That's actually the problem - Linux hot swap is virtually non-functional for SCSI.  You can write into the proper places in /proc, then remove and rescan to get a new drive up, but I've found that the resulting OS state is flaky.  This is true of the latest 2.6 kernels and LSI and Adaptec SCSI controllers.

The problems I've seen are  with Linux, not the controllers.
Interesting, I have had zero problems with Linux and SATA with LSI controllers and hot plug. I wonder what the difference is. The LSI controller even though SATA just uses the scsi driver.
