Yes, I just repeated it to test.

I had 9755 installed.  I then installed 9742.

modprobe.conf look like this:
# nvidia kernel module
alias char-major-195 nvidia-1_0-9742
alias nvidia nvidia-1_0-9742

without running nvidia-graphics switch.

I rebooted and got this:
NVRM: API mismatch: the client has the version 1.0-9742, but
NVRM: this kernel module has the version 1.0-9755.  Please
NVRM: make sure that this kernel module and all NVIDIA driver
NVRM: components have the same version.
NVRM: API mismatch: the client has the version 1.0-9742, but
NVRM: this kernel module has the version 1.0-9755.  Please

so I ran nvidia-graphics-switch 9742, checked modeprobe.conf which still
has 9742, and rebooted

NVRM: API mismatch: the client has the version 1.0-9742, but
NVRM: this kernel module has the version 1.0-9755.  Please
NVRM: make sure that this kernel module and all NVIDIA driver

I removed 9742 and went back to 9755.




I agree. That is what was happening to me. I did no make the test
again because there is no 9746 driver for 2.6.20, and in this case, 9755
is alone in the kernel and is loaded appropriately. But I could have booted
using an older kernel to make the test again. However, I just not did it
yet.

I just would like to add that /etc/ld.so.conf was also correct and all the
symbolic links in /usr/lib/xorg/modules/, as far as I remember.

Maybe something has changed in recent kernels?
