Windows 7: Windows 7 on Pentium-M

Does anyone installed Windows 7 beta on a laptop with Pentium-M + 855PM Chipset?

I installed Windows 7 on such a laptop but there's WEI remarks and the CPU always running at 100% max frequency even I upgrade all the drivers through Windows Update and change the settings in Power Options

yeah，it's right，i installed Windows 7 on my ibm t40 .First,you can install the newest Mobile Intel(R) Express Chipset drivers,then disable the auto update,choose
"check updates but let me choose weather to download an install them"

after this the CPU can change the frequency according to the usage? can you give a link to download? because I'm confused which driver is right for my laptop and windows 7.

i tried to install the lateset chipset driver, but it said: does not support this operation system.

try this one
http://downloadmirror.intel.com/10884/eng/INF_allOS_9.1.0.1012_PV.exe

this is the adress of the intel chipset drivers

next for ibm t40 only:

and you must install audio card driver,
http://drivers.mydrivers.com/download/211-84766-Realtek-ALC650-ALC655-ALC658-ALC850-AC97-6.0.1.6285-For-Vista-Vista-64/

then,install the ati 7500 video card driver,The Radeon 9000 driver works for the Radeon 7500 card
so screen resolution-advanced settings-properties--drivers-update driver-browse my computer.....-list-seek the driver for 9000 series,install it

now,it works well

What is the speed/performance like on the T40? Especially in comparison to XP? I'm thinking about trying 7 out on my R40... bit worried about the 16MB graphics though...
