Comment(by Quozl):

 This isn't developer key behaviour being changed, once I change to using

 I can explain the significant delay you see in the field.  It is not a

 The code that captures the ESC key when the laptop is unlocked, runs
 before any device or filesystem access occurs.  So it has a very
 predictable response.  Pressing ESC as soon as the XO icon appears or the
 startup sound begins will always work.

 But the code that captures the key when the laptop is locked, with a
 developer key present, runs after a device and filesystem search for
 /security/develop.sig.  Since the NAND FLASH on XO-1 has a jffs2
 filesystem, the time it takes to open this filesystem can be large, and
 can vary.
