Make sense ?


Yes.  For 2.6.21.  As I've always said.
But for 2.6.20, we are only HALFWAY there, and all these /new/ bugs exist as a result.
Your patch makes far more sense for 2.6.21, where the "halfway to salvation" state, and associated rough edges, is not exposed to users.
Fixing the resource tree was only half the solution, since the drivers that /use/ the resource tree now need updating.
