Yeah sorry, dumb mistake.

I am using cpufreq but I think its good for lowering cpu frequency, not
raising it.
The default frequency /proc/cpufreq shows is cpu MHz : 1300.088. I was
wondering if its just faulty dmi tables reporting 1.4 Ghz or that for
some reason sony decided to use the cpu at 1.3 Ghz, or that it was
designed to be able to overclock it to 1.4Ghz and the bios just doesn't
give that option.

I don't use PCMCIA so I don't know about that but all the rest works
even with isa disabled.
