lsmod should show kernel dri/drm modules, and glxinfo/xdpyinfo should
give more info. Basically, if 3D stuff works, you have DRI enabled.

No idea, I don't know what pm-utils contains, if you have s2ram on your
system it might be part of it. (That, or it's a package containing other stuff.)
Suspend is mainly implemented by the kernel, it elaborates with X by
doing a VT switch (virtual consoel switch, like happens when you do
Ctrl+Alt+F1), and the video drivers can hook into that and do whatever
is needed to save and restore video state.
s2ram is a helper application that helps with restoring the video state
after resume (read that page I gave a link to).
I've no idea what KDE's desktop power management control does,
as I'm not using KDE.
