Hmmm, I'm running nvidia-kernel 6629-r4 and nvidia-glx 6629-r6 on a
amd64 system without any problems.

I don't have the specific versions that were failing for me, as I'm not at home right now, but as I mentioned there was a thread on this recently, here are some quotes from that thread:

OP:

I can't find out what I'm doing wrong. I have a nvidia card (GeForce FX
5200) and I managed to launch the X server with the nv driver. When I
try to use the nvidia driver, the server aborts, complaining about not
finding a usable screen section.



The following file is the one that works (with nv). To try nvidia, I
made two changes: Load "glx" (instead of dri) and nvidia (as driver)
instead of nv. Something is missing... (Didn't change identifiers and
such.)


I emerged nvidia/kernel and nvidia-glx for good measure, issued "modprobe nvidia",
modules-update, openglx-update nvidia...
Kernel is 2.6.13-gentoo-r3.

The last lines of /var/log/Xorg.0.log :

[29] 0 0 0x000003c0 - 0x000003df (0x20) IS[B]
(II) Setting vga for screen 0.
(**) NVIDIA(0): Depth 24, (--) framebuffer bpp 32
(==) NVIDIA(0): RGB weight 888
(==) NVIDIA(0): Default visual is TrueColor

(EE) NVIDIA(0): Failed to initialize the NVIDIA kernel module!
(EE) NVIDIA(0): *** Aborting ***
(II) UnloadModule: "nvidia"
(EE) Screen(s) found, but none have a usable configuration.

Fatal server error:
no screens found


Followup by OP:
It seems it's a known bug. I emerged nvidia-kernel and nvidia-glx with
ACCEPT_KEYWORDS="~x86" and it works now.


Comment from list member:

One thing to check is do you have any /dev/nv* devices? There was a
thread in the forums on this which has a script for recreating them and
another thread on this list in which I posted it.


Reply by OP:

That was it. I found the thread, that's why I emerged the masked
versions of the driver (see my reply to myself).
BTW: the suggestion to put the script in /etc/conf.d/local.start seems
somewhat strange: doesn't /etc/init.d/local get executed after all other
scripts in the default runlevel? Doesn't this mean that the script would
be started _after_ the X server?

***********************************************************************

Maybe this isn't the problem in this specific case, I don't know, but it's possible that it is. I don't remember whether or not the OP in this case specified whether or not the configuration was working with the default nv driver or not, that should be the first step in troubleshooting this. Once the nv driver works with the configuration, if the nvidia driver does not, that's a resonable indication that there is something wrong with the nvidia module.
