I think the %10 and %11 thing must go. There is no point to the
frequency coded notation. This is NOT an IP address. There is no point
to dividing it that way. Any arbitrary split will be fine, and
allocating the first 2k to dynamic devices when no real machine has
more than 20 or 30 devices at most is not reasonable.

Well, that isn't in the current projects list... and even if it were,
real machines don't have 2000 devices on the bus.
