Hi there
The question is a bit difficult to answer easily as the answer depends on what your expectation is for such a tool.
In Gnome (available both in Fedora and Debian based distros like Ubuntu and Mint) You can monitor the power usage by a Power Statistics application.
Here is a screenshot of an older version:

If You want to tweak the system to use a less energy-consuming profile, that's a bit more manual work.
There is an application called Jupiter which has some nice feature possible to access from the GUI - but it maybe don't have the one-button-eco-mode feature that the Eco utility supports.
From the console you should be able to run powertop - a pretty cool program that enables you to set certain devices into a power-saving mode.
Find info about PowerTOP here: Link:

For the more adventurous user there has been a lot of talk about the ASPM feature in Linux vs BIOS.
ASPM will save some power but is by default not enabled in recent kernels due issues with bad BIOS'es not reporting ASPM support in a proper way.
You may pass boot parameters to the kernel before booting and this is were You manually force ASPM support to be enabled.
The parameter you should use is this one:
pcie_aspm=force
Read about it here: Link:
HERE
You should realize though that if your BIOS is not supporting this feature, the unit may hang.
No big problem, just restart and do not pass the kernel parameter and the issue is gone.
If you notice your PC works well with the ASPM enabled, you should consider making the parameter a permanent setting. Depending on if you're using LILO, GRUB or GRUB2 the methods vary.
I have the pcie_aspm forced all the time and this works fine on my Toshiba's.
Good luck and remember to have fun!

I'll give those a try once the warranty expires or i'm sure all the hardware is properly supported (whichever comes first).
