Can you post your 'dmesg' and 'free' output ?

 Wow! Greedy bastards from HP :) Looks like a 32MB RAM
 board without any glue logic. 

> So, is anyone willing/able to make a 128MB expansion board?

Can somebody knowledgeable comment the last sentence ?

: The dynamic memory interface supports four 32-bit wide banks of fast-page or 
: EDO asynchronous DRAMs. Each bank is allocated 128 Mbyte of the internal 
: memory map. However, the actual size of each bank is dependent on the
: particular DRAM configuration used. If multiple banks are populated, each
: must be identical in size and configuration.
