It's not that I am not interested nor completely new to this, it's just that
I am currently a little short on time for things like these.  The last time
I checked, the Linux people have just started to make use of DMA maps, a
concept that other OS/architecture combos employed for years already.  Is
that what is used in the TiBooks to allocate DMA channels ?
