Bug description:
  On Lucid with the Natty backport kernel and also on the precise kernel
  the removal of the Sierra Wireless 250U Data Card causes both gnome
  and reboots to hang and a kernel trace to be displayed on the console.
  A work around was found by including the firmware found in the sprint
  developers pack in /lib/firmware. I did not see the same behavior on
  the current Lucid kernel, as a matter of fact, it appears to operate
  just fine with no firmware at all.  Also of note, the firmware from
  http://code.google.com/p/bcm-wimax/ improved gnome/kernel stability
  but the device only works the first time it is plugged in, and
  modprobe hangs indefinitely when trying to remove the bcm_wimax
  module.

  Work around:
  http://whebsite.com/media/downloads/Sprint4GDeveloperPack-1.6.1.2.2.tar.gz
  Unpack the above.  Inside are "Rel_6.1.2.2_USB-Updated.zip" and "Sprint4GMBBUtilities.tar.gz"; unpack them.  Find "macxvi.cfg-PowerSaveOff-Rel_6.1.2.2_USB-Updated" and "macxvi350.bin".  Copy the former to "/lib/firmware/macxvi.cfg" and the latter to "/lib/firmware/macxvi200.bin" (note the name change!).
