Yes, I have read these documents and tried to follow them. For this
driver, there is two more file type than described in sysfs-interface,
continous and enable. However, as they doesn't need to be accessed
through lm-sensors I think it should not be a problem. They are mostly
there if you screwed up the device.

Yes I know they are not very common however I sometimes use them. Since
I switched to a 2.6 kernel, I can't use them anymore, that's why I am
interested by ported them.
BTW, I don't know really how to follow the sysfs-interface document with
the PCF8591. The current driver in lm-sensors creates the following
files under /proc:
ain_conf: used to configure the 4 inputs (single ended, differential,
etc.)
ch[0-3]: the 4 input channels, representing a voltage
aout: the output channel, representing a voltage
aout_enable: enable/disable the output channel
I think I can map ch[0-3] to in[0-3] but for the others I don't know
what to do. If you have an idea, let me know.
