-in order to get it to apply cleanly to the released 2.6.15 codebase
-and to put the Kconfig stuff in a more reasonable place in the tree.
-Actually, I think Kconfig should probably separate the notion of the
-touchscreen driver and the AC97-MCP layer thing; but that problem is
-basically in the underlying mcp-based ucb1x00 driver layout in the
-first place.
