1142N-A-K9 AP will not power up via POE Injector DPSN-35FB-A

If this has been asked before I apologize however my searches didnt find any answers:

I have a AIR-LAP-1242N-A-K9 with BootIOS 12.4.23.0, IOS 12.4(23c)JA10 and software version 7.0.252.0 connecting to controller 4402 (I know its old)...This AP will not power up using the DPSN-35FB-A power injector.  It is my understanding this injector is the equivalent of the pwrinj4=.

However I have another AIR-LAP-1242N-A-K9 running BootIOS 12.4.18.0, IOS 12.4(23c)JA10 and software version 7.0.252.0 connecting to the same controller and it will power up using the DPSN-35FB-A power injector.

From what I can see the only differences are the Boot IOS.  if I telnet to the 12.4.18 AP, the ? shows me a depth of options I would have expected, however the 12.4.23 AP does not.  

The 12.4.23 AP will power on using a PowerDine 3001 injector but only gets 100Mbps.  Kind of a waste of the N protocol.

I have tried disabling CDP, enabling pre-standard 802.3af and overide on the injector state.  No success in getting this AP to boot. 

The question, is it possible the bootloader difference is enough to keep the AP from powering via the injector?
