[1] One line summary of the problem:

Maximum CPU frequency incorrect and there is no CPU scaling

[2] Full description of the problem/report:

I have an Acer Aspire 5720 and it is set up to dual boot Vista and 
ubuntu 14.04 LTS. From new the laptop came with an Intel T7300 2.00 Ghz 
CPU and 1 GB DDR2 RAM. A few weeks ago I upgraded to 4 GB RAM, which 
works perfectly, and a few days ago I upgraded to an Intel T9300 2.5 Ghz 
CPU.

The BIOS (up to date), Vista and ubuntu all recognise the CPU correctly as:

"Intel(R) Core(TM)2 Duo CPU T9300 @ 2.50 GHz".

Vista allows the CPU to run correctly at up to 2.5 Ghz and will step the 
CPU speed lower when not needed, depending on which power settings are 
chosen.

The problem is that ubuntu will only allow the CPU to run at a fixed 
frequency of 2.4 Ghz, which is incorrect as it's a 2.5Ghz CPU, and there 
is no stepping to lower the CPU frequency when max frequency is not needed.

"cpupower frequency-info" in a terminal returns:

analyzing CPU 0:
driver: acpi-cpufreq
CPUs which run at the same hardware frequency: 0
CPUs which need to have their frequency coordinated by software: 0
maximum transition latency: 10.0 us.
hardware limits: 2.40 GHz - 2.40 GHz
available frequency steps: 2.40 GHz, 2.40 GHz
available cpufreq governors: conservative, ondemand, userspace, 
powersave, performance
current policy: frequency should be within 2.40 GHz and 2.40 GHz.
The governor "ondemand" may decide which speed to use
within this range.
current CPU frequency is 2.40 GHz.
cpufreq stats: 2.40 GHz:10.47%, 2.40 GHz:89.53% (12799)
boost state support:
Supported: yes
Active: yes

I have tried using ondemand, performance and powersave - nothing makes 
any difference. I have also installed CPU Frequency Scaling Indicator 
(which shows only 2.4 Ghz and 2.4 Ghz (turbo mode) as available 
frequencies) and I have also tried TLP but nothing makes any difference.

According to this website:

http://www.phoronix.com/scan.php?page=article&item=mobile_penryn&num=3

the T9300 CPU should have the following frequency steps:

2.50 GHz, 2.00 GHz, 1.60 GHz, 1.20 GHz and 800 MHz.

I have also reproduced this issue on 12.04.3 LTS Precise Pangolin 
running from a USB stick, and also on 14.04 LTS with the latest 
mainstream kernel.
