We've always had more than 256Mb RAM but not been able to make one kernel that would access it all on both >256Mb and <=256Mb builds. This patch http://git.kernel.org/?p=linux/kernel/git/marex/pxa-linux-2.6.git;a=commit;h=9ee18023466d30e3847a77c82a1e776fb3cf02fc enables exactly that for another pxa270 board. I _think_ it's exactly what we need and is all of 10 lines. But I could be wrong. Wookey -- Principal hats: Linaro, Emdebian, Wookware, Balloonboard, ARM http://wookware.org/
