You could also get msr-tools package/tool and try to set frequencies yourself
(best without acpi-cpufreq loaded):
rdmsr 0x198
shows the current freq.
rdmsr 0x199
shows the current ctl register.
Be careful, only change the lower 0-15 bits and write your wanted frequency in
there. There is one bit (32) that modifies Turbo Mode behavior.

This should do it (untested):
wrmsr 0x199 $((`rdmsr 0x199` + $DESIRED_FREQ))
DESIRED_FREQ can be a value from scaling_available_frequencies.
