Very OT, but I'll bite :) Find out what you want to use the machine for
FIRST - my laptop is mostly to get me away from the noise of my desk
with lots of computers around, to act as an MP3 player and to double as
a Windows machine for my daughter's homework.

Upgradeable probably doesn't count: people throw away machines rather
than upgrade processors. On a laptop, memory is the only thing worth 
adding after you've bought it IMHO. The premium needed to
replace a high end desktop  [3.8G Pentium / Dual core Opteron 4G memory
and 500GB disk] would be huge: people buy laptops for portability / convenience and put up with limited battery life and a high price for low spec.

32M should be enough for most things: taking memory from shared system
memory will normally take it out of RAM.

Almost certainly infeasible.

Probably infeasible

See above: laptops are not desktops.

The useful thing about Centrino from a wireless point of view is that
Intel support their chipsets well under Linux especially the iw2100 and
2200 chipsets.

Hope this helps,
