Could you please point out why is too tsi148-specific?

The point here is that the driver should know *nothing* about
windows, etc. What it should just know is:
- I want a mapping of a certain size to VME address X
The struct provides exactly this.

Also, could you please send me (off-list) documentation of the
Universe bridge? It'd be useful for the work on the generic layer.
