Mandriva Beats OpenSUSE
Susan Linton, the distro expert from Linux.com and founder of TuxMachines, is in with the verdict.
Overall Winner
In our little just-for-fun comparison, we the judges find that Mandriva wins by 4 categories to 2. But to the original question the answer would be to go buy the Mandriva Power Pack or try PCLOS or ALT Linux in which advanced power saving feature do work out of the box. Also, YMMV.
However, don’t forget that both openSUSE and Mandriva are both nice distros. This little article is highly subjective and you may not agree. That’s okay. I love them both.
Winner: Mandriva 2008.0
For the record, I never got the impression that Susan was prejudiced against Novell. In fact, she has always seemed like a long-time SUSE user (when not distro hopping). Her comparison confirms the fact that OpenSUSE is not essential for desktop Linux to reach the masses. We could do better even with Mandriva, which explicitly rejected and eliminated the possibility of selling out to an abusive monopoly.
Highlight: Novell was the first to acknowledge that Microsoft FUD tactics had substance. Novell then used anti-Linux FUD to market itself. 
Highlight: Xandros let Microsoft make patent claims and brag about (paid-for) OOXML support. 
Highlight: Linspire's CEO not only fell into Microsoft arms, but he also assisted the company's attack on GNU/Linux. 
Highlight: Microsoft craves pseudo (proprietary) standards and gets its way using proxies and influence which it buys. 
Highlight: The invasion into the open source world is intended to leave Linux companies neglected, due to financial incentives from Microsoft. 
Analysis: Xen, an open source hypervisor, possibly fell victim to Microsoft's aggressive (and stealthy) acquisition-by-proxy strategy.
