[SOLVED] Intel C2Q not able to cpufreq': No such device

See Topic. Cpufreq worked some month ago (i used trayfreq which today just throws an floating point exception, but that is another story).

When booting with acpi=off, acpi_cpufreq will be loaded. When booting with acpi=on (default), it is not possible to load the module ("there is no such device").

CPU: Intel Core 2 Quad q9450
Mainboard: MSI Neo P35-FR

DAEMONS=(syslog-ng network netfs hal @crond @alsa @fam @samba @cups @vboxdrv @nginx @mysqld @sshd !smbnetfs !mpd cpufreq)
