I'm working on the same issue right now, and I got as far as that: I
can write one byte to the EEPROM an read it, except I do it
consecutively. In debug mode it works though, so I guess, I got some
timing problems. Does anybody have experiences with that?

Do you mean the sample software provided by Philips? The apppication
example is a bit tricky, because it deals with a temperature sensor
with a strange protocol and the commands are determined in the handler
it self. 

I found an application note for a LPC9XX and an I/O expander modul:

It's structured very clearly (application/driver) so I could change it
for the LPC2XXX easily following the steps Mark described.
