regression: oops with usb bcm203x bluetooth dongle 2.6.5

[Soeren Sonnenburg]

Hi.

This dongle used to work fine (at least till 2.6.3) and still does if I
remove the bcm203x kernel module and manually (or via hotplug) use the
bluefw program to upload the firmware.

This dongle gives me an oops on _insert_.
Mass storage devices/HID work fine.

This is on a ppc machine with xmon support compiled in. So if you need
more infos than this backtrace, please say so.
