6-in-1 card reader: works in fc1 and not in fc2

I have reported the problem in bugzilla:

https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=124139

The issue appears to be that usb-storage isn't scanning for partitions 
after getting a heads-up about a device being plugged in.

I own plenty of card readers (and other usb-storage devices like cameras) 
that all worked up to FC1, but don't work in FC2 - all of them are 
correctly detected, the correct drivers/modules are loaded, but no 
partition scan takes place, so the devices cannot be mounted.

e.g.

SCSI subsystem initialized
usb 2-2: new full speed USB device using address 21
Initializing USB Mass Storage driver...
scsi1 : SCSI emulation for USB Mass Storage devices
  Vendor: SanDisk   Model: Cruzer            Rev: 2.00
  Type:   Direct-Access                      ANSI SCSI revision: 02
Attached scsi removable disk sda at scsi1, channel 0, id 0, lun 0
USB Mass Storage device found at 22

after this, the kernel should scan for partitions /dev/sda1, /dev/sda2, 
etc. but it doesnt. This is the same whether I use a single LUN device 
like the Cruzer (as shown above) or a multi-LUN device like a 7-in-1 card 
reader.

If this bug is confirmed, I'd treat it with a sense of urgency - these 
days, just about everyone uses USB-storage devices, and this is a definite 
show-stopper.

I believe that Arjan has done something to make things work in his
experimental kernels, but those are for RHEL, and apparently have pretty
dismal desktop performance (xmms stutters, etc.)
