I did send you my preliminary buildroot quite some time ago,
and published a script which downloads and build buildroot 
one week ago.

This new script will build the following board:
* at91rm9200df,  at91sam9260dfc, at91sam9261ek, at91sam9263ek
(Fragments of avr32 support is there but not tested lately)

Except for the root file system (in ext2/jffs2) it also builds:

* linux-2.6.20.4    now defined in target/linux/Config.in; Makefile.in
* u-boot-1.2.0
* at91bootstrap-2.3
* datflashboot-1.05

everything "configurable" or board dependent builds in the 

target_build_$BR2_ARCH)/$(BR2_HOSTNAME)

(Linux/U-boot/Busybox/root/at91bootstrap/dataflashboot)

and results are published in

binaries/$(BR2_HOSTNAME)

Note that BR2_HOSTNAME is used instead of BR2_BOARD_NAME
since they refer to two different things.
You can build several versions of the same board so 
you can have several .config files with a common BR2_BOARD_NAME
but BR2_HOSTNAME differs.

What else is required to move on ?
