Hi,
I'll soon start an ARM based project (at91sam9g45), and am looking into booting options. I normally use PPC, so I'm not really familiar with the finer details of U-Boot on ARM. I would like to use a failsafe setup with 2x U-Boot images in NOR flash, and a mini bootloader (probably at91bootstrap based) to decide which to use. For that to work nicely, U-Boot would have to be PIC (pre-relocation).

Sure, but having a single image (certainly for a ping-pong system, E.G. where you keep the current and previous image) a single position independent image is nicer.
Does that work with u-boot on at91 given !SKIP_RELOCATE_UBOOT & !CONFIG_LOWLEVEL_INIT?
