i can't get nouveau to start, the screen just stays dark and i have to
hard-reset the computer. I am using Debian unstable/experimental and the
git-version of nouveau & drm. Details see attached Xorg.log.

How about kernel logs? (with drm debug=1)

I've recently made several changes that ought to improve the behaviour on
geforce2 cards to not lock-up the chip, so if you can update nouveau and try
again (new log if it's still not working) that would help.

If you find it is still hanging, mounting as "sync" the partition
containing
your logs (ie if /var/log is in the partition mounted at /, do "mount / -o
remount,sync", will get a log with info right up to the crash.

Also, an mmiotrace of this card using the nvidia proprietary driver would be
very interesting.  Detailed instructions are at
http://nouveau.freedesktop.org/wiki/MmioTrace , but for a sufficiently new
kernel:

mount -t debugfs debugfs <somewhere>
echo mmiotrace > <somewhere>/tracing/current_tracer
modprobe nvidia
cat <somewhere>/tracing/trace_pipe > ~/mmiotrace
startx

before starting X will suffice (assuming the nvidia proprietary driver to
previously be installed and working).

The current nouveau is claiming when trying to load drm:

/usr/bin/X: symbol lookup error: /usr/lib/modules/drivers//nouveau_drv.so:
undefined symbol: NVReadVgaCrtc

which i can, btw, not find in any log but only in the error-screen when x does
not load.

it could take a while before i have time to do a mmiotrace.

Some Makefiles changed, you need to re-run autogen.sh on your checkout or start
over with a new checkout.

If you have time to do a register dump while using the proprietary driver, that
would be useful too (I'm guessing the kernel compilation for mmiotrace is
the
cause of the time problem).  Simply:
git clone git://anongit.freedesktop.org/~stuart/radeontool; cd radeontool; make

then run "./radeontool regs > dump" in an xterm while using the
nvidia driver.

It appears that this bug report has laid dormant for quite a while. Sorry we
haven't gotten to it. Since we fix bugs all the time, chances are pretty
good
that your issue has been fixed with the latest software. Please give it a shot.
(Linux kernel 3.10.7, xf86-video-nouveau 1.0.9, mesa 9.1.6, or their git
versions.) If upgrading to the latest isn't an option for you, your
distro's
bugzilla is probably the right destination for your bug report.

In an effort to clean up our bug list, we're pre-emptively closing all bugs
that haven't seen updates since 2011. If the original issue remains, please
make sure to provide fresh info, see http://nouveau.freedesktop.org/wiki/Bugs/
for what we need to see, and re-open this one.

Thanks,

The Nouveau Team
