The patient: Intel Mac Pro, three and a half years old, running OS  
10.6.8, 300 GB startup disk with 160 GB free.

(Sigh)  The patient was performing well yesterday afternoon until...

I opened System Preferences and changed the Energy settings to 3  
hours each (they had been set for shorter intervals.  Then did a  
Restart.

There was the usual startup chime, the pale grey screen with the  
apple, then a blue screen.  There it remained.  The little windmill  
cursor appeared at intervals and went away at intervals.  The blue  
screen flickered a bit, like it really was trying to start up.

Remedies I tried:
Starting up holding the S key - no change.
Starting up holding the C key (the external backup disk, not Time  
Machine, was attached - it is supposed to be bootable) - no change.
Starting up holding the option key (there is a Bootcamp partition).   
Yes, I can boot into windows. (Arrrgghhh).

While in windows, I opened the cd tray and put the Snow Leopard disk  
in, then tried a restart holding the C key again.  Used the SL disk  
to repair permissions - there  were only about a dozen repairs, all  
having to do with System/Core Services/ Remote Management.  Also  
clicked Repair Disk.  The message said the disk was OK.

Tried another restart - no change.  Started up on the SL disk again,  
repaired permissions again - the same items  were 'repaired.'

Used an old laptop to access Apple support, worked through the  
Express Lane.  Resetting the SMC sounded promising, so I went through  
the steps of that, but no change.  That was a far as I could go with  
Express Lane without paying for a phone consultation.

Unfortunately, I don't have a current copy of Disk Warrior, or I  
would have tried that.

So I am really hoping WAMUG members can help.
