Hm, nah, I'm using -b to specify my root, and in fact, it's on sd2h (that's
the reason why I introduced the possibility to specify a partition other
than the a-partition to be your root partition:-)

I'll look into your scheme in more detail tonight, but right now I think, this
is WAYS too much overhead at ipl6... Couldn't your dispatcher live at ipl4,
and do all the nice things with priority queues etc. at that level? It would
still require protection for stuff like malloc, but at least if wouldn't run
at an ipl that the rest of the system isn't even aware of exists...
