+# The downside is that each module is larger, and a system that uses

+# (but a system that uses exactly one module will use the same amount of
+# memory).
#
-# Note 2! The CFLAGS definitions are now inherited from the
-# parent makes..
+# The upside is that if the DRM support library ever becomes insufficient
+# for new families of cards, a new library can be implemented for those new
+# cards without impacting the drivers for the old cards. This is significant,
+# because testing architectural changes to old cards may be impossible, and
+# may delay the implementation of a better architecture. We've traded slight
+# memory waste (in the dual-head case) for greatly improved long-term

+# libs-objs are included in every module so that radical changes to the
+# architecture of the DRM support library can be made at a later time.
+#
+# The downside is that each module is larger, and a system that uses
+# more than one module (i.e., a dual-head system) will use more memory
+# (but a system that uses exactly one module will use the same amount of
+# memory).
#
-# Note 2! The CFLAGS definitions are now inherited from the
-# parent makes..
+# The upside is that if the DRM support library ever becomes insufficient
+# for new families of cards, a new library can be implemented for those new
+# cards without impacting the drivers for the old cards. This is significant,
+# because testing architectural changes to old cards may be impossible, and
+# may delay the implementation of a better architecture. We've traded slight
+# memory waste (in the dual-head case) for greatly improved long-term
+# maintainability.
