Hey Naushad, thanks for the response. Any idea *why* it won't work? Is
there no backwards compatability for the DDR2 RAM (thought I read something
in my searches abt DDR2 being backwards compatible for DDR...)?
Like I said, in my case it looks like they just doubled the clock timings so
why wouldn't the faster stuff just step down to the slower speeds and work
fine since everything else is literally *exactly* the same? Not doubting
you or what you're saying; guess I'm just still being irrationally hopefully
at the awesomeness of the deal and wanting it to work for me and clutching
at straws. *le sigh*
So do you think if I tried it putting in the DDR2 it would cause my machine
any problems (since I've ordered it and it's getting here Tues) or should I
not even go there...? :P

No it will not work.
The reason DDR1 memory is expensive is because of demand (or lack thereof).
40 bucks may be a lot, but if it gives you 1 more year out of your laptop
then it may be a good deal.
