The kernel config (2.6.19-1.2895) does not include the K7 PowerNow module. Without this module, battery life is reduced significantly and this laptop runs too hot. # CONFIG_X86_POWERNOW_K7 is not set
We actually build powernow-k7 into the kernel, not as a module, and it *is* enabled in the i686 kernel: $ rpm -q --qf='%{name}-%{version}-%{release}.%{arch}\n' kernel kernel-2.6.18-1.2869.fc6.i686 kernel-2.6.19-1.2895.fc6.i686 $ grep POWERNOW_K7 /boot/config-2.6.19-1.2895.fc6 CONFIG_X86_POWERNOW_K7=y CONFIG_X86_POWERNOW_K7_ACPI=y I suspect you may have the i586 kernel installed instead of the i686 one.
