I don't know if my problem is related to this bug... but, I have a Toshiba Tecra S4-122 notebook, with a Core2 Duo T7200 (2.0Ghz).
The available frequencies reported are wrong:

attila@blackbird:~$ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies
2000000 1660000 1330000 1000000 65535000
attila@blackbird:~$ cat /sys/devices/system/cpu/cpu1/cpufreq/scaling_available_frequencies
2000000 1660000 1330000 1000000 65535000

(notice the 65.535 Ghz! ... which is also reported by the gnome cpufreq applet)

Some more details (attached are dmesg and syslog logs):
