It dies in vbeDoEDID() called by GeodeDoDDC().

My previous statement about delays making a difference was false.  I
messed up an if() statement by pasting a debug line between the if() and
the block, and not protected it with braces.  This inadvertently set the 
pGeode->useVGA to FALSE and prevented the call to GeodeDoDDC().  Ooops.
