This machine doesn't have hal; when I kill udevd still doesn't help.

Yes, something's using that drive, be it a program, a module (unlikely), 
or something that is compiled directly in the kernel (for example, 
md/raid1).
But what is it?

Kernel knows it, as it refuses to remove the module (via rmmod), but how 
to tell kernel to share this knowledge with me?
