X41 Tablet with Windows 8 Won't Rotate

[JRMX]

After installing Windows 8 on my X41 (1867) tablet and running Lenovo Windows Update and 8jvu37ww.exe, auto rotate does not work and neither do any of the any of the tablet keys. Curiously, there was no problem with the Windows 8 Preview version. After running 8jvu37ww.exe, I get the error message "This program does not support this system."

Auto rotate is resolved by installing 7jgk09ww.exe, but Hot Button Integration [8jvu37ww.exe] still gives error message.

OT: how did you get Win8 running on your X41t? Mine is complaining about missing CPU features and does not let me install...
