Marigold here, after several more months of lurking.

Actually, I believe that DD was alerted by Arthur.  If you look at 
the order of letters arriving by owl post at the Dursleys' (OotP, 
chpt. 2), you'll see that the first one is from the Ministry.  The 
next one is from Arthur telling Harry that DD has just arrived at the 
Ministry and is attempting to sort things out.  So, because of his 
work and work-connections, Arthur immediately found out what had 
happened and alerted DD using the mysterious method that DD mentions 
in chpt. 37, "The Lost Prophesy" (pg. 830).

As to the other part about DD knowing the Dursleys might try to order 
Harry out of the house, DD answers that himself.  Chpt. 37 (pg. 8360):

"Wait," said Harry.  "Wait a moment."
He sat up straighter in his chair, staring at Dumbledore.
"You sent that Howler.  You told her to remember --- it was your 
voice ---"
"I thought," said Dumbledore, inclining his head slightly, "that she 
might need reminding of the pact that she had sealed by taking you.  
I suspected the dementor attack might have awoken her to the dangers 
of having you as a surrogate son."
