I've tried to find the reason behind my problem, but didn't manage to. The problem: Can't start acpi_cpufreq ("No such device"), but p4_cpuclock driver works well. In this case there is no c-state management (cpu is always in C0). I've decompiled dsdt - only some warnings about methods related to pci. Checked _OSI() - nothing special. There are errors in dmesg, related to cpu's info (truncated): ----- [ 17.045653] ACPI Warning (tbutils-0217): Incorrect checksum in table [SSDT] - E6, should be 38 [20070126] ....
