It wouldn't surprise me for a PCI (or AGP) chip to request a memory
window of 16MB regardless of what is actually onboard.  So I'd believe
X, not lspci.

You mean GHz.  /proc/cpuinfo should report its current speed
accurately.  It might have multiple speed settings, in which case what
you want is a kernel compiled with 'cpufreq' support - or possibly just
with ACPI, including the CPU sub-module.  Then you'll need a userspace
application to control this.  "apt-cache search cpufreq" turns up three
packages in Debian unstable that claim to do this sort of thing - take
your pick.

I'm guessing that's for your 16-bit PCMCIA interface, along with your
PS/2 ports (built-in keyboard and whatever-mouse-replacement), plus
your serial, parallel and IrDA (infrared) ports, if present.
