I've worked around the issue using 'cpufreq' at the CLI to manually select my governor & max CPU speed. I'd bet that your governor is set to 'ondemand' as I believe this is the default for all processors (for whatever reason). You can check this by running "#cpufreq-info" at the CLI after you have installed the cpufrequtils rpm. That command will give you a readout of everything going on such as your CPU stepping frequencies, the current governor, the current frequency, etc. What's weird about this issue, is that I didn't have this problem when using this same laptop & Mandriva 2009.1-2010. On the contrary, with Mandriva my laptop does not have a "Suspend to Disk" feature...go figure.
