Same effect on Thinkpad X61s (Intel Graphics Media Accelerator X3100). Blank black screen with just mouse pointer visible after closing and opening the lid back (no suspend necessary), happens maybe once in 20 times. Input works—i can move mouse pointer, also cursor changes when over a text field (or I guess it's a text field, it's in the middle of screen, where a password dialog should be).
