I had this problem when I upgraded from 9.04 to 9.10. I use a Dell Inspiron 9300 and I found that when I unplug the laptop and run on battery suspend works fine. But when I try to suspend while plugged in I get the same problem as you described. (Black screen with a single underscore in the top left, fans stay running and power light and blue- tooth light stays on.)
