Interesting idea. Can you load kernel modules on-demand (as opposed to 
the init script)?


I guess I could do a system call to killall the PVR tasks. I'm still not 
certain how to dismount the active filesystems from a currently-running 
Linux.

But... how do I know the memory chunk used is contiguous?

I guessed it'd come down to a quick clobber action. After all, there's 
no concept of "returning to Linux" except by power-cycling. [there's no 
reset button ;-)]


Best wishes,
