Hello,

Recently upgraded to gutsy from feisty and the problems started. Cant get frequency scaling to work.
Both acpi-cpufreq.ko and speedstep-centrino.ko gives error "No such device". Tried applying linux-phc-0.3.0, no luck.
Read somewhere that disabling "Long battery mode" in bios solves problem for acpi-cpufreq.ko, but for me it didn't change a think.
Frequency scaling worked fine with 2.6.20-16-generic using speedstep-centrino module. Its Fujitsu-siemens Amilo M m3438g.
Actually , making processor work at full speed its enough for me, because now its just 800. No modules, responsible for frequency scaling, are loaded, no software like cpudyn, powernowd or cpufreq are installed, but still 800
After modprobing acpi-cpufreq.ko and speedstep-centrino.ko dmesg reports:
[ 214.240000] speedstep_centrino: no version for "struct_module" found: kernel tainted.

I had this problem as well, and I have the same processor as you. I usually use Kubuntu, but thought I'd give Gnome a try and did a fresh install of Ubuntu Gutsy. I messed with it for hours and couldn't get it working, so I reinstalled Kubuntu since KDE is more familiar to me. I thought it would have the same problem, but strangely enough frequency scaling is working perfectly, even though I'm also using the same kernel.

I don't know why it would work in Kubuntu and not in Ubuntu, but I might try installing the ubuntu-desktop packages on top of Kubuntu and see if it works. Wish I could offer more help.
