There already is work underway to port Haiku to ARM so don't be surprised if there is something bootable in the next year or so.
Question: It is my understanding that BeOS/Haiku uses the 'HALT' instruction to lower power use when the CPU is idle and waiting for an interrupt, does the ARM have such an instruction/mode and if it does how much power is used compared to normal CPU needs?
I am thinking in term of a large number of cores when a number of them will sit idle when there is not a heavy load on the system.

From what I understand Haiku is based on the NewOS kernel which includes support inside it for multiplatformness.
The problem with Linux is the need to get rid of HAL and replace it with something that doesn't depend on a constant cycle of polling. Once HAL is replaced you'll find that battery life will improve considerably when combined with the improvements that are slated for 2.6.32.
That said, does anybody know of a good mainstream disto release for the ARM architecture?
Canonical are working on a version of Ubuntu for ARM.
Debian have had an ARM port for ages.

My ASUS 901 runs Ubuntu so for me, to see a netbook running one of these chips would be fantastic. I want raw performance AND power efficiency, I don't see why I should settle for just one of the two.
I'm hoping that when it's ready, they port Haiku to ARM as then I think all my netbook dreams would come true :-). Until then, Linux will do fine.
