After installing 10.5.2 - three main side effects!

Question

Hi all,
After upgrading 10.5.2 and graphics update I am experiencing three main problems, and just one of them seems to be a reported bug as far as I know:
1. *The black screen after going to sleep mode*. I found some threads in this forum and I have to check it out.
2. what it seems to be a weird one: I can set brightness screen up, but when I shut down the system does not seem to keep track of this setting and *goes back to full brightness on start up*... it may seems a minor bug, but believe me, it is starting to be pretty annoying.
3. When the computer is turned off, most of times if I plug it in (either to the wall socket or to the magsafe) *suddenly starts up by itself*.
By the way, my laptop is a 2.4 MBP, and yes, I zapped PRAM many times and did not work.
I hope you can help.
Best regards,
Antonio

Given the operating system updates are written the same for each similar computer system, and people with the exact same machines have had no problem whatsoever, does it not suggest there must be some contributing factor you have failed to consider? It would to me. That's what they teach in logic. And computers whether you like it or not are logical devices. They only work on zeros and ones. Either they do, or they don't work. The only way they can sometimes not work, while other times work is if some contributing factor of something which is unexpected creates a problem. What can that be? Given Apple's officially spec'ing these systems for a range of Macs, you would think that Apple has indeed tested with each of those spec'ed Macs as virgin systems. You can't possibly think that Apple has tested for all 24 thousand possible software packages in the space of time given, since even 64 software packages tested together offer more combinations of possible software packages than there are seconds in the age of the universe. So given logical possibilities, you must come to the conclusion you have tripped up one of those improbable combinations of software/hardware that Apple has not had a chance to test for yet, nor the third party developer. The update as an update is functional on a virgin system, and that's all you can ever expect it to be. It does not mean that the update is at fault for not being a working system. Apple clearly outlines what it expects of software developers here:
http://developer.apple.com/
If they don't follow those outlined steps to the letter, that's when you can run into problems.
Data corruption which is also an operating system independent issue can also lead to problems.
Let's not blame the operating system, and let's find the contributing factor causing the issue at hand.
To say the truth, this is quite surprising... didn't you read about so many troubles after upgrade? many people has got the blank screen after sleep mode and many hasn't, and so on... even I have read about people doing downgrades and not experiencing those problems. In my case, everything started from the very moment I made the upgrade.
I am not very experienced with Apple, but I've been dealing with computers since 20 years ago, I am an SAP principal consultant... and you tell me that the same software has to work in the same way with the same machine?
I had a Burt Simpsons saying but.. maybe is not the time neither the place
Thanks. but I will go to regular forums, they were always truly helpful.
