Soldered onto the board are four Nanya NT5DS16M16CS DDR RAM chips. The specific variant of these chips is NT5DS16M16CS-5U; I wasn't able to find data specific to this chip, but its cousin - the NT5DS16M16CS-5T - is 16Mb per chip (I think; the datasheet's a bit confusing).
And then... is that a BIOS chip? And a CMOS battery? Given these, getting a dump of the low-level firmware should be straightforward. Stay tuned for that.
