/var/log/dmesg from fedora
as there are some initial lines missing from my dmesg output, this is what
fedora had stored...

does it work if you boot with mem=2G in kernel command line?

yes it works!
(with mem=2G)
But memory is already low on my system, so limiting it to 2G is not an option
for me.
This is an 64 bit system. So i am wondering why i have a 32bit (2G?) problem?

Your card has problems addressing memory above 2G.
As a temporary workaround you can apply patch from bug 46557.

Marcin:
As I mentioned in 46557, I'm not convinced that the problem is hardware. It
could easily be some widening bug in C code. It smells like sign-extension of
a 32 bit quantity that should be zero-extended. But it could be the truncation
of a wider-than-32-bit quantity to 32 bits. And, of course, it could be
hardware.
Why would the 32-bit Linux have no trouble with the identical hardware?

I can add another data point, which indicates it is not the hardware.
This card works "flawless" with the nvidia driver since 4.5 years. It is only
my curiosity, why i try nouveau from time to time.
As recompiling the kernel on every new update from fedora is not an option i am
going back to the nvidia driver.
But at least i know now how to install a "fresh" fedora (mem=2G), so your help
is greatly appreciated!

D. Hugh Redelmeier:
If you can prove it's "widening bug", please do (by fixing it).
Memory used by the kernel in 32-bit mode is allocated in first GB, so you can't
hit this bug there.
Dietmar:
Nvidia driver may:
a) init the hardware in a way we don't, fixing this bug
b) workaround it internally by allocating memory in first 2G
