Greetings,

On the topic of power management, I did a simple hack with the NetBSD kernel so 
that brightness/contrast is ok on reset, and then boots NetBSD again. See http:/
/kirk.modevia.com/100_0140.avi

Right now I keep pieces of CE in RAM by reducing NetBSD memory usage by 5MB - 
4MB from the front of RAM and 1MB from the back (kernel is based at 
0xC0400000). Actually not this much is needed to be reserved at all, but I 
couldn't get the kernel to boot unless it was aligned to 4MB. Another 
alternative is to restore these parts of RAM when shutting down / rebooting / 
suspending (don't know if that would work with a hardware soft reset). If that 
is done, it obviates the need for a partitioned CF as well.

This prevents a hard reset when it jumps to 0x0, so I think this probably has 
implications for power management. It would still be necessary to convince it 
to resume rather than soft reset, but I don't know enough about the NetBSD 
kernel nor ARM architecture to play with it... Hope it helps someone who does!
