Is there anything you can post? (If there's too much to remember, you can photograph your screen, import the image, upload it to a remote host, and link to it.)
I'm sure how to go about the posting et cetera but I thought I'd take a shot and transcribe it.
I did a Verbose start and it was much different than previously. Where there had been a screenful before, this time there were only about 6 or 7 lines. The shot was too blurry to read.
I did another Verbose start and this time I was back to a screenful. Three shots but all too blurry. This is something that'll have to wait until I get a tripod out.
Mean while I did remove a lot of drivers - all drivers that were not Canon and all of the Canon drivers except these:
CanonIJBJS700.ppd.gz
CanonIJDS700.ppd.gz
CanonIJMX700series.ppd.gz
CanonIJMX710series.ppd.gz
A restart took about 5 or 6 minutes less time than the last few.

00:20 Grey screen with Apple and the spinning device
01:35 Blue Screen
09:10 Log-in screen
I then found in the Launch Agents folder:
com.zeobit.MacKeeper.Helper.plist
Com.Adobe.ARM. (a bunch of numbers and letters) .plist
I removed both and restarted. This time the restart was much longer and more convoluted.

I have restored the 3 Canon drivers. The two plists (MacKeeper and Adobe) have not returned.
