Umm...  sorry... Don't know much of AT91...
- Do not know if AT91 will be immune to hacking
- Do not know much about Atmel, ST chips.  Have not study their
  datasheet yet.  I'm still loyalist to philips parts. (And I hope
  Philips do not screw up on the CRP)
- Do not know if AT91 chips have better CRP mechanism.
- Very seldom visiting the AT91 forum.
- I'm NOT a chip hacker.  Limited knowledge on hacking.
- This is not the forum for AT91.  
- I use the ARM7 chips for simple control replacing 8-bit uC
- I do not disassemble LPC2xxx bootloader, never attempt to hack
  the LPC2xxx CRP in the past.  Do not even know how hack-able 
  is the LPC2xxx part I'm using.  AT91?? completely no idea.
- I take/accept Philips description of "no simple way to hack the
  LPC2xxx"
- We cannot even get the LPC2xxx CRP proven hack-able here. 
  So far everything are just "speculations"....=> I'm not too
   concerned about AT91's CRP at the moment
- If somebody here shows LPC2xxx CRP hack-able, may be I will
  consider switching to AT91
- Only thing=> I believe there will be more AT91 chip hackers in 
  the far east as Atmel microcontroller traditionally is stronger
  there.  =>More people/resources trying to hack the chip   :)

Sorry, could not answer your question...hope someone familiar
with AT91/AVR and who did some in depth study of LPC2xxx BootLoader, 
LPC2xxx CRP mechanisms/loopholes could answer your question... :)

(Please help to stick to main topic/issue else thread is getting
more and more diverted... )
