I think I have not been clear enough; the built-in switching function in the kernel is not related to the bug reported here. It has not changed since the 2.6.2x versions, AFAIK.
It just confirmed the fact that usb_modeswitch could not be involved with this bug in any way.
My assumption (rather gut-oriented) is that either the probing of modem-manager or some change in the usb-storage driver may cause a firmware crash or a device reset, probably due to a previously unexposed problem with the firmware itself.
