AMD Radeon HD 6750M in 2011 MBP-Graphics Issues-Second Life

Question

Since there were no responses to my question, I have re-worded it.  Second Life runs fine on my late 2009 iMac i7 with it's ATI Radeon HD 4850 graphics card. SL freezes at boot up on my new 2011 MBP with it's more powerful graphics card.  Message is that "Your system contains a graphics card that is unknown at this time.  This is often the case with hardware we haven't had a chance to test.  Second Life will most likely run properly but you may need to adjust  your graphics settings to something more appropriate..."  Nope...I have to Option Command, Esc to force quit.  Feedback on this minor issue appreciated.

When you have the problem, note the exact time: hour, minute, second.   
These instructions must be carried out as an administrator. If you have only one user account, you are the administrator.
☞ Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
Open LaunchPad. Click Utilities, then Console in the icon grid.
The title of the Console window should be All Messages. If it isn't, select
          SYSTEM LOG QUERIES ▹ All Messages
from the log list on the left. If you don't see that list, select
          View ▹ Show Log List
from the menu bar at the top of the screen.
Each message in the log begins with the date and time when it was entered. Scroll back to the time you noted above. Select the messages entered from then until the end of the episode, or until they start to repeat, whichever comes first. Copy the messages to the Clipboard by pressing the key combination command-C. Paste into a reply to this message by pressing command-V.
The log contains a vast amount of information, almost all of it useless for solving any particular problem. When posting a log extract, be selective. A few dozen lines are almost always more than enough.
Please don't indiscriminately dump thousands of lines from the log into this discussion.
Please don't post screenshots of log messages—post the text.
Some private information, such as your name, may appear in the log. Anonymize before posting.
