The fonts.dir warnings aren't unusual.  Gentoo's xorg build goes thru the
normal font dirs automatically, creating font.dir files (a kind of index
file used by the font rendering), but some will be empty dirs, simply
placeholders in case you merge any fonts of that type, while others are
"super-dirs", that is, they don't contain any fonts (and thus no font.dir)
themselves, only subdirs with fonts in them.  So, the font.dir warnings
aren't anything to worry about at all.

The APM thing is legacy power management.  You get the warning because you
probably have newer equipment that doesn't use that old power management
stuff any more.  You can eliminate the warning by placing An 'Option
"NoPM"' line in your xorg, in 'Section "ServerFlags"'.  The newer power
management stuff should continue to operate normally, or it does here,
anyway.

If you are running NVidia's proprietary drivers, I believe you should have
the DRI (Direct Rendering Interface) extension disabled.  It's normally
enabled for ATI, I believe, so you probably have an 'Load "dri"' line in
the 'Section "Module"' from the same old ATI.  Simply commenting that
line with a # at the beginning of it should eliminate those errors.

See NVidia's README file for more details.  (My info on NVidia and DRI is
from a couple years ago when I used to run their proprietaryware drivers. 
It may have changed since then.  Again, their README file is quite
detailed and helpful.  It's well worth taking a gander at, if you haven't
already done so.)

In any case, DRI is I believe 3D rendering.  It's not used in normal 2D X
mode, and as I said, NVidia doesn't use it as they use their own system
for 3D mode, so it's safe to turn off, but that's why X seems to start
even with those errors.

Disregard that.  It's not relevant in this case, because the NV that would
otherwise refer to non-volatile refers to NVidia, and a guess would be RM
is Rendering Module, or some such, so NVRM is simply referring to the
NVidia driver module, or whatever that RM stands for, not to
non-volatile-RAM, as would likely be the case in other contexts.

I didn't look at them in any depth, only enough to see it does seem to be
your error, and in at least some of the cases, the posters ended up using
a different driver version to avoid the issue.  I'm guessing that's  what
you are likely to end up doing as well, tho it's possible a kernel
incompatibility and you may have to change kernel versions instead or as
well.
