What your PPC does is called "suspend-to-ram" (shutting off everything except the RAM and supporting circuits). If the iLiad would be able to do that, it could go to STR after switching the page, using the advantage of e-ink displays to keep the content without needing energy.

This is not a problem of using a Linux OS. But I think, like with normal PCs you are driver-wise better off with Windows, simply cause the hardware vendors or MIcrosoft provide you with drivers. Since I'm not into embedded Windows or Linux, I can't really say what the situation is there, just speculation.

Just take a Sharp Zaurus or a Siemens SIMPad (running OpenSIMPad), both are running linux, have a touchscreen and do suspend-to-ram. The iLiad however seems to have some hardware that doesn't make it easy to implement this, but I would not think it is totally impossible. I don't want to repeat it ever and ever but we all know that someone from iRex already mentioned in their forum that they have trouble with some of the hardware components.

Also your idea with the 2 boot options is probably not impossible, however it would need to be implemented. Most embedded devices have only one boot mode or something like "reset-to-factory" by pressing one button at boot-up.
