The dmesg output

I have a NVIDIA GeForce 8600GT graphics card. I'm using Gentoo on a AMD64
machine with a custom built 3.5 kernel.

I've been using nouveau for more than a year by now without any kind of
problems. Yet, since I enabled the last kernel options I needed to get 3D
hardware acceleration, I'm having some issues.

When closing applications like web browsers or video players the X server
suddenly hangs (I cannot even move the pointer) and, after a few seconds, it
crashes and I see a TTY console. Then, I think, gdm tries to restart it and
after a few seconds I have again some graphics on the screen which often is a
corrupted image of what I was seeing before the crash. Then X crashes again,
gdm tries to restart it and so on.

When I'm on the TTYs I'm having some keyboard issues (keys double-typed or
missed) but otherwise they work fine, so I was able to log in and get some
dmesg output and X logs, which I'm attaching.

This issue only appears after I suspend and resume the PC. I can trigger this
behavior almost at will after a resume but I'm not able to do it before. It
also seems to be related to Xorg drivers and/or 3D, since I didn't encounter it
before activating hardware acceleration and it only affects the X server, even
after a restart, while having no effect at all on TTYs.

If you need more detailed information just let me know.
