I've asked about this issue on the ps2 linux forums and somebody
came up with this document:
http://lc.linux.or.jp/lc2001/papers/tas-ps2-paper.pdf

See also this releated thread on the linux-mips list:
http://www.linux-mips.org/archives/linux-mips/2002-01/msg00278.html

I'm not fluent in Japanese or MIPS assembly, so I won't comment
on these. Just posting the links :)

Bye, Chris.
