I have not had a look, but it would be a reasonable assumption that it is the ASIC chip on the other side of the bus... the only problem is that I think the markings on the ASIC chip seems very similar between the UK and US models... so it might not be the case...
eg:
UK: TMS1 REV A ASIC-00001-000 0036WX016
US: TMS1 REV A ASIC-00001-000 9919KX001

Your slave-to-slave idea might be possible... although I am not sure how the timing channel would be affected by this. The following is a short run-down on what I2S is, and where to find the datasheet:

I2S = Inter-IC Sound

A high speed serial bus standard for use with digital audio and/or video communications developed by Philips in 1986 and based around their I2C chip-to-chip communication standard (aka 12S), were it differs from most such serial systems is that high resolution clocking signal is sent alongside the data itself to ensure synchronisation and reduce or eliminate problems such as Jitter. It was originally designed for on board communications between electronic parts as can be seen from the name and is used as such on everything from high end digital televisions to mobile phones, but has more recently been seen used on high end audio as an external interconnect standard in the form of I2S Enhanced. Basically an IS2 bus consists of 3 signal paths, one has 2 channels of audio or video data multiplexed onto it using TDM, the second channel has clock info and the third is a word select line.

If you wish to go down a completely different track you might want to try a F15a board (Tomek found this)... you are likely to need the 38.9MHz version - price is somewhere around the NZ$40 mark. It's Polish, so contact, payment and shipping could be a hassle... I was in Poland a year back and still have some money was going to look into this before the whole MSP3410D swapout became viable. (FYI: banks here will neither provide nor purchase Zloty so I need to use it somewhere )
