amd64, 2.6.7: several problems

Hi folks,

I've got some questions about amd64.

/proc/cpuinfo returns

processor : 0
vendor_id : AuthenticAMD
cpu family : 15
model : 12
model name : AMD Athlon(tm) 64 Processor 3200+
stepping : 0
cpu MHz : 2194.366
cache size : 512 KB
fpu : yes
fpu_exception : yes
cpuid level : 1
wp : yes
flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 syscall nx mmxext lm 3dnowext 3dnow
bogomips : 4341.76
TLB size : 1088 4K pages
clflush size : 64
cache_alignment : 64
address sizes : 40 bits physical, 48 bits virtual
power management: ts fid vid ttp

Please check the cache size. It _should_ be 1024 kB, at least that was written
on the bill I've got. Is this correct?

Next powernow-k8 refuses to load on my PC:

# modprobe powernow-k8
FATAL: Error inserting powernow_k8 (/lib/modules/2.6.7/kernel/arch/x86_64/kernel/cpufreq/powernow-k8.ko): No such device

This is strange. AFAIK all amd64 CPUs do have Powernow.
The ACPI modules (expecially processor), freq_table and cpuid
were all loaded. Whats wrong here?

I tried to compile a static powernow-k8, but that gave me the error

arch/x86_64/kernel/built-in.o(.init.text+0x7d9a): In function `powernowk8_cpu_init':
: undefined reference to `acpi_processor_register_performance'
arch/x86_64/kernel/built-in.o(.init.text+0x7f39): In function `powernowk8_cpu_init':
: undefined reference to `acpi_processor_unregister_performance'
arch/x86_64/kernel/built-in.o(.exit.text+0x33): In function `powernowk8_cpu_exit':
: undefined reference to `acpi_processor_unregister_performance'
make[1]: *** [.tmp_vmlinux1] Error 1
make[1]: Leaving directory `/usr/src/kernel-source-2.6.7'
make: *** [stamp-build] Error 2

The ACPI Processor stuff was still set to "build module", so it
seems that there is a missing dependency in menuconfig.

Any help would be highly appreciated
