Boot takes 20 minutes, no bluetooth
I'm looking for some pointers on how to diagnose the issues I am seeing on my 24" iMac (early 2009, 2.66 A1225). Here is a synopsis of what I am experiencing:
1) Boot up takes about 20 minutes, or more... generally the machine sits at the "white screen" for most of this time.
2) When machine comes up, the blue tooth interface simply does not exist.
I've taken a few basic steps like resetting PRAM ... I did boot from the CD to run the AHT but that yielded nothing, in fact, it hung. I let it run over night... about 18 hours straight.
So, I am trying looking for some advice on some things I could look at that could give me a clue what's going on - honestly, at this point the machine is not worth taking to a shop. *IF* I can get it to work it will either be my 7 year old daughter's first computer, or dedicated to hosting my film scanner which requires a fire-wire interface (and for which I have a Mac mini that could do the same thing).
For all practical purposes, this could easily just be sent to recycling but I'd like to use it as a practical learning experience.
Right now, I have two working theories:
1) It's a problem on the logic board (from what I can tell, expensive part if you can find it)
2) it's a problem with the blue tooth module (I am assuming that is a daughter-board)
I am also curious, in terms of circuit cards, what functions of this model iMac are built on to the logic board and which are provided by daughter-boards?

About the same time the following messages started appearing in the system log - regularly and repeatedly:

As for reinstalling, booting in safe mode, etc... all of that has become problematic. For example, I tried booting in safe mode - held down shift until the Apple logo appeared (about 5 min) - machine rebooted.
Tried booting from diagnostic disk - held down "D" key during boot until apple logo appeared. Machine rebooted.
Tried reinstalling OS... same thing when booting from install media.
I've reset NVRAM and SMC. No changes.
I set up boot-args for verbose mode, nothing of note - most of the delay occurs during just getting to the point where the OS starts to load.
The one and only time I was ever able to get it to boot off the diagnostic disk and ran AHT, it hung... I was able to start the test and it appeared to be progressing, but 18 hours later had not made any progress.

As for turning off Bluetooth that is really part of the problem - I can't turn it off or on, the Bluetooth device is not found. I have tried a couple of remedies for this (deleting the Bluetooth property list, reset in SMC, etc)... So, effectively it is off. I suspect the USB errors I am seeting are somewhat related to that.
As of now, I can't even boot the machine - since my last attempt to reboot (in safe mode), it has been continually restarting itself.
My goal right now is just to get it up to a point where I could run some kind of diagnostics rather than resorting to pure guess work to figure out what is wrong.

just set boot-args to always boot verbose and safe... (-v -x) - now it is just continually rebooting. It spends a fair amount of time "loading drivers" and then restarts... 3 times in a row so far. Ugh. Make that 4.
