Ccing debian-kernel for maks, and debian-boot for Frans, or whoever will commit my patches.

I get : $ ls /lib/modules/2.6.17-2-powerpc/kernel/drivers/macintosh/ ans-lcd.ko apm_emu.ko therm_adt746x.ko therm_windtunnel.ko windfarm_core.ko Does windfarm_core make sense to build on 32bit ? I suppose we can load adt746x and windtunnel, what about the other two ? > You also need to make sure cpufreq_64 is enabled for them to work. So, i should add some of the below modules : /lib/modules/2.6.17-2-powerpc64/kernel/drivers/cpufreq/cpufreq_conservative.ko /lib/modules/2.6.17-2-powerpc64/kernel/drivers/cpufreq/cpufreq_ondemand.ko /lib/modules/2.6.17-2-powerpc64/kernel/drivers/cpufreq/cpufreq_powersave.ko /lib/modules/2.6.17-2-powerpc64/kernel/drivers/cpufreq/cpufreq_stats.ko /lib/modules/2.6.17-2-powerpc64/kernel/drivers/cpufreq/cpufreq_userspace.ko And also load them ?

Ok, but in the meantime, we will work from the above list. Friendly, Sven Luther -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
