It seems that cardbus handles things fine but individual drivers may be lacking in suspend/resume support. That's a good testing approach, btw. If you find the dc(4) driver seems to be the culprit, the next step is to go through any datasheets and other OS drivers to see if you can find what we're doing differently. -- Nate
