The graphics update hasn't fixed other, older issues either, see:

So glad this is not just me. Mine has been all jacked up using my 1920x1200 external in clamshell. Same problems as described above. Hopefully this will get dealt with right away. I thought I was sitting pretty after updating the mini, so I did the laptop soon after.
I am afraid to even plug in my external now...
Odd
This was working fine for me yesterday during the day. Last night I unhooked my external display used as a conventional laptop and then powered down. When I restarted today and tried to hook up my external monitor the settings had been lost and the monitor was not mirroring.
That fixed, I hooked my monitor entered sleep mode after mirroring and when I tried waking from sleep - nothing. MBP is waking up and then keeps trying to wake up with no information going to the display.
My external display is 1280x1024, I would be interested to hear if any of you are still having this problem.
I havent had any issues with clamshell and external since the first time. I have NOT updated the graphics firmware or whatever. Who else updated 10.5.2 but did not update the graphic?
What is the best way to get back to 10.5.2 WITHOUT this freaking Leopard Graphics Update that is screwing up everyone's laptops?
This is a travesty that a function SO entwined with the basic functionality of this laptop was not properly tested and has ruined the experience of a number of us Apple supporters - WITHOUT ANY RESPONSE FROM APPLE.
I'm steamed.
