Gui related (or anything related) device driver: yes. This is perfectly
okay, as long as this "driver" does not draw windows or manages clipping
rectangles (because clipping is somthing that _is_ dependent on certain
gui, isn't it?).

Hm, for example? What improvements you propose for the XDD layer?

I guess that he just means something that MiNT is currently missing,
e.g. block devices. "Modules" is a word that describes XDD and XFS files,
currently.

Hm, can you elaborate?

Obviously. Parameter block is okay. Not okay is accesing it from other
process, because this is illegal. So, we keep parameter block and access
it from the same process, i.e. from a lib running in user context. I have
an impression that most of the discutants agree on that.

Indeed.

Yes, I have an impression that we are talking about it all the time.
