ERROR: Unable to load the kernel module 'nvidia.ko'. This happens most
frequently when this kernel module was built against the wrong or
improperly configured kernel sources, with a version of gcc that differs
from the one used to build the target kernel, or if a driver such as
rivafb/nvidiafb is present and prevents the NVIDIA kernel module from
obtaining ownership of the NVIDIA graphics device(s).
Are you using the generic kernel? I have a GeForce TI 4600. The installer (same one you used) built a module for me which worked without incident with a new install of Slackware 12.1.
You should make sure that rivafb and nvidiafb are absent from `lsmod` output. I would guess your problem is caused by the lack of SMP kernels -- it looks like you only have the generic and huge kernels (and not the generic-smp and huge-smp kernels) installed. From CHANGES_AND_HINTS.TXT on your install CD/DVD or available from your favourite mirror:

the generic kernels - see /boot/README.initrd for instructions.

For most systems, you should use the generic SMP kernel if it will run,
even if your system is not SMP-capable. Some newer hardware needs the
local APIC enabled in the SMP kernel, and theoretically there should not be
a performance penalty with using the SMP-capable kernel on a uniprocessor
machine, as the SMP kernel tests for this and makes necessary adjustments.
Furthermore, the kernel sources shipped with Slackware are configured for
SMP usage, so you won't have to modify those to build external modules
(such as NVidia or ATI proprietary drivers) if you use the SMP kernel.
If you decide to use one of the non-SMP kernels, you will need to follow the
instructions in /extra/linux-2.6.24.5-nosmp-sdk/README.TXT to modify your
kernel sources for non-SMP usage. Note that this only applies if you are
using the Slackware-provided non-SMP kernel - if you build a custom kernel,
the symlinks at /lib/modules/$(uname -r)/{build,source} will point to the
correct kernel source so long as you don't (re)move it.
If you decide to use one of the huge kernels anyway, you will encounter
errors like this:
kobject_add failed for uhci_hcd with -EEXIST, don't try to register
These occur because the respective drivers are compiled statically into the
huge kernels but udev tries to load them anyway. These errors should be safe
to ignore, but if you really don't want them to appear, you can blacklist the
modules that try to load in /etc/modprobe.d/blacklist. However, make sure you
remove them from the blacklist if you ever decide to use the (recommended)
generic kernels.
I would HIGHLY recommend using the huge-smp or generic-smp kernel over the non-SMP kernels (and I would further recommend the generic-smp kernel over the huge-smp kernel). Note that the generic-smp kernel requires the use of an initial ramdisk (initrd) -- see /boot/README.initrd for more information. Search the forum for information on how to switch to the generic-smp kernel (it has been explained many times). Note that you will have to install the huge-smp and generic-smp kernels (at least one of them, anyway) since they're not currently installed on your system. They are both located in the a/ series on your install CD/DVD (CD 1) or at your favourite mirror.
