OK, this is an MCP61 board. We're now using softreset instead of
hardreset on hotplug and apparently that doesn't work. Thing is that:
http://bugzilla.kernel.org/show_bug.cgi?id=11195
reported that hardreset was borked on that controller. Seems kind of
contradictory..
/if only NVidia could be consistent in its hardware bugs..
