*** This bug is a security vulnerability ***

This problem was fixed in 10.10 with an update.  While not using nomodeset, sometime incorrect commands would be sent to the display causing errors such as entering low-power mode, flickering or simply going blank.  In particular, my Samsung television enters a standby mode that is otherwise inaccessible by the consumer.  It turns on and off repeatedly as a result of a command being sent by the display driver.  Honestly, I didn't know it was possible, but you may want to look at the fix for 10.10 as the solution for 11.04 and maybe exploit this error to gain a little more functionality of HDMI televisions.
I consider this bug a security vulnerability because it causes otherwise inaccessible functions of the display hardware to become accessible at the hardware level.
