I found this in the data sheet that agrees with you:

	Before performing the jump to the application in internal SRAM,
	all the PIOs and peripherals used in the boot
	program are set to their reset state.

I will throw some hours after this in the weekend to see if I can get
it up and running.

Agree, except that I need find a nice way to add whatever I do to the
current at91 stuff. But that is part of the fun.
