well, I suppose you understand my problem... This stupid annoying modprobe is filing up my log with waste. This should be the "apm" module (plz, don't reply saying to enable "apm") but since my computer use ACPI, I don't care about apm and I can't use it in the same time of acpi. I taked a look at my system and it seems to be the nvidia drivers who try to modprobe this useless module. Since I don't want apm, is their a way to shut up nvidia or just to keep these useless lines out of my log files??

add the following to your /etc/modules.conf

alias char-major-10-134 off

HTH

given solution turns off the messages completely, but might want to try and add onto /etc/modules.conf:
alias char-major-10-134 apm
If you check in /usr/src/linux-2.4/Documentation/devices.txt, 10 - 134 refers to Advanced Power Management

Considering I posted this in 2001, I don't really need it anymore. In any case, the laptop I had at that time is long dead now.
