Install Linux. 
IIRC AmigaKit and Vesalia used to sell single sided simms.
Amigakit has some double sided 128's.
I ended up getting this off ebay. Let you know how it works out. Micron ram used to be really good memory back in they day.

Actually, it also may be wiser buying the SCSI adapter than spending some huge sum for some obscure SIMM if I want more. I really don't need SCSI as I am happy with my FastATA and eSATA port. I'm just glad you sent the 16mb chip as I would have nothing otherwise.
As far as Linux goes, and I know enough about Linux (was previously employed doing kernel development for a device running 2.4 ARM kernel and used a Linux development workstations all day long for cross-compiling) and the answer is... ummm..... NO...
Linux is fine... Linux may even be at the point that it is user-friendly. I don't know. Just I don't see the point of running it on a gaming notebook. What killer app for Linux takes advantage 8GB ram, 8 hardware threads and a 460 GTX video board? "Dude, watch how fast I can recompile my kernel..."
Also there really is no equivalent of WinUAE under Linux (or OSX).
cheers!
