For example of grafting legacy ARM peripherals to Cortex-M3 you can look at
LPC-17xx port Bug 1001114 being combined with LPC-2xxx peripherals Bug 1001115
.

However if larger re-organization of AT91 port is considered, I would propose
moving AT91 peripherals out of ARM devs subdirectories (except for peripherals
based on ARM IP, if any). Something like this:

packages-+
         +-devs+
               +-serial+
                       +-AT91-+
                              +-current-+...

Also following scheme could be considered (although radical) if same devices
are shared among all AT91 platforms:

packages-+
         +-devs-+
                +-Atmel(AT91)-+
                              +-serial-+...
                              +-ethernet-+...
                              +-spi-+...
