I did something similar with my 4G iPod a few years back.
The hard drive died so I installed a 60 gig CF card with an adapter.
It works ok but the CF card is too slow so the iPod pauses occasionally to buffer the data.
I've been meaning to get a faster CF card but I might just check out...

Replacing the screen required disassembling the entire laptop.
Apple used an absolutely stupid number of different sized screws.

I first tried some double-sided foam tape but it wouldn't hold long term.
These pictures were taken before I was completely finished.
I also had to get an ATX extension cable to be...

Although theoretically the battery you have should work as well.
It is likely your Portable will need...
Yes, Motorola had their own daughter cards. They used a socket that could accept a BGA part.
I have some photos of the card we used with the P58 motherboards on my other computer, I'm out of town right now.
Here's a photo of two systems I set up to do accelerated life testing with the 7448.
