Description of problem:

HAL keeps reading from the USB floppy I have. This is wearing the
floppy and makes irritating sounds. This used not to be the case
in older versions of Fedora.

Version-Release number of selected component (if applicable):

hal-0.5.10-0.git20070731.fc8
kernel-2.6.23-0.70.rc1.git13.fc8

How reproducible:

Seems 100% reproducible, but perhaps you need a certain hardware.

Steps to Reproduce:
1. Plug a floppy into USB. Insert a disc.
2. Listen for HAL reading.
  
Actual results:

Constant operation of floppy.

Expected results:

Not reading the media after the first time.

Additional info:

I think something broke the revalidation in sd.c in case of removables.
I have verified with strace that a mere open() causes re-reading of
the media where it didn't before:

[root@simbelmyne zaitcev]# strace -p 2784
