I get a very similar oops backtrace, but from a different cause. Whenever I plug in my Zaurus for the /second/ time (i.e., plug it in, let usbnet find it, unplug it, then plug it in again), I get the attached oops backtrace. This did not occur with 2.6.3; unsure about 2.6.4.
Just like in the bluetooth case, usb_disable_interface is causing the oops, and is being called by usb_set_interface. I tried the patch in the comments of your linked bug, however that did not fix the problem.
