The cpufreq-* modules are loaded, I tried both available Fedora kernels
(2.6.31.5-96.fc12.x86_64 and
2.6.31.1-56.fc12.x86_64, acpitool --cpu says :
CPU type : AMD Athlon(tm) 64 Processor 3800+
CPU speed : 2400.392 MHz
Cache size : 512 KB
Bogomips : 4800.78
Processor ID : 0
Bus mastering control : yes
Power management : no
Throttling control : no
Limit interface : no
Active C-state : C0
C-states (incl. C0) : 0
But...in works in $OTHER_DISTRO and /proc/cpuinfo says
processor : 0
vendor_id : AuthenticAMD
cpu family : 15

model name : AMD Athlon(tm) 64 Processor 3800+

cpu MHz : 2400.392

fpu_exception : yes

cr8_legacy
bogomips : 4800.78
TLB size : 1024 4K pages
clflush size : 64
cache_alignment : 64
address sizes : 40 bits physical, 48 bits virtual
power management: ts fid vid ttp tm stc
...so it obviously should support cpu frequency scaling. Any ideas?
