P-state tables are probably loaded from separate SSDT tables "CPU0IST" and
"CPU1IST". You can download 'em with something like this:
# dmesg | grep IST
ACPI: SSDT BFD30566, 01FB (r1 PmRef CPU0IST 3000 INTL 20030224)
^addr ^length
# acpidump --addr 0xBFD30566 --length 0x1FB > cpu0ist
# iasl -d cpu0ist
Then paste cpu0ist.dsl somewhere.
