No, I think I was mistaken. The manual is for more models than the
specific one I own. Sorry about the confusion. Here is /proc/cpuinfo
anyway:

cpu family      : 15

I bought it about a month ago. I have only tested ACPI briefly.
Activating it in a standard 2.4 kernel doesn't work very well (battery
status not available, lots of errors in dmesg during boot.) I haven't
tested the latest patches from Intel yet.
