As usuall, also wince has their usage. To be honest, I use linux only for
some specific tasks, and WinCE still does a good job in what they were
designed for.

That still not completely clear to me, but it seems yes. Resume is same as
start. The problem is same as for previous - coding, and understanding how
to wake up kernel on jornada. I am not that sure it is working properly
even with flashboard and bootldr.

I never saw anything like that in past, but IMHO the CF is too slow to be
used as flash memory (it's IDE). But I could be wrong
