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:

processor       : 0
vendor_id       : GenuineIntel
cpu family      : 15
model           : 1
model name      : Intel(R) Pentium(R) 4 CPU 1.70GHz
stepping        : 2
cpu MHz         : 1694.536
cache size      : 256 KB
fdiv_bug        : no
hlt_bug         : no
f00f_bug        : no
coma_bug        : no
fpu             : yes
fpu_exception   : yes
cpuid level     : 2

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.
