These are pretty harmless. Functions over a certain size are not
inlined even if the programmer says to. gcc is just telling the
programmer they were ignored.

This driver one of the problem children of the tree. The cards it
supports have generally been out of production for quite some time and
there aren't a whole lot of users left (certaintly not a lot of users
who are going to want to run 5.x on their hardware :).

Any statement of the form "X is the one, true Y" is FALSE.
