dmesg after normal startup on Arch x86_64, prior to startx

$ dmesg | grep -i chipset
[ 19.583102] nouveau [ DEVICE][0000:01:00.0] Chipset: GT215 (NVA3)

Description:
I can only successfully `startx` if I modprobe nouveau with no acceleration
(`nouveau.noaccel=1` appended to kernel line or `options nouveau noaccel=1` in
/etc/modprobe.d/nouveau.conf).
With noaccel=0 (default), I get a GPU lockup message and borked X session (see
attached photo of screen).

Things tried:
--- firmware: I tried the nouveau-fw packages from Arch Linux's AUR, which
simply packages the firmware instructions here:
<a href="http://nouveau.freedesktop.org/wiki/VideoAcceleration/">http://nouveau.freedesktop.org/wiki/VideoAcceleration/</a>. I have diff'ed the
contents of /lib/firmware/nouveau/ and /tmp/nouveau/vuc-* + /tmp/nouveau/nv*,
and they are identical.
>From what I can tell, NVA3 (NV50 Tesla family) shouldn't need 3D Accel firmware
(<a href="http://nouveau.freedesktop.org/wiki/InstallDRM/">http://nouveau.freedesktop.org/wiki/InstallDRM/</a>, 3D-accel firmware section):
"NV40 - NV50: No firmware needed. The Nouveau driver generates the ctxprogs and
related state internally (commits 48c6dfb8 and 266229a5)."
With firmware in /lib/firmware/nouveau, I've tried with and without
`nouveau.config=NvGrUseFW=1`, though per the Kernel Parameters page
(<a href="http://nouveau.freedesktop.org/wiki/KernelModuleParameters/">http://nouveau.freedesktop.org/wiki/KernelModuleParameters/</a>), this only seems
relevant for NVC0.
--- Per <a class="bz_bug_link
bz_status_RESOLVED bz_closed"
title="RESOLVED FIXED - GF108 (NVC1) GPU lockup"
href="show_bug.cgi?id=69488">bug 69488</a>, I tried with `nouveau.rumpm=0` and still get the lockup, not
to mention that report suggests this is fixed in 3.13, and I'm on 3.14</pre>
