You're right, it doesn't make any sense, but there it is.  The exact
same kernel package, except on i386 and with all the Gnobe dependencies
installed, worked for the same USB disk.  But plugging the disk into my
amd64 system did not work.  It didn't even load the usbstorage module.
If I then loaded usbstorage by hand, the usb<->scsi-disk connection
wasn't made at all (I'm running SATA disks, so sd_mod and friends were
already loaded).  Furthermore, the hub on my Dell 2407WFP was completely
non-functional -- it didn't even show up in usbview.

I built a kernel from stable-git, and bingo all was working.
My guess as to why it works is that scsi and scsi disk support aren't
modules in my custom kernel.  I figured with sd_mod and scsi_mod being,
well, modules, in the Debian kernel, something like hald or some other
obnoxious daemon I don't want was "helping" the scsi subsystem rescan
or whatever.
