I'm surprised you couldn't get it to work. As far as I know, the driver
is precisely made for people who build a board according to Simon Vogl's
schematics. If you provide details about the failures, we might try to

Great. Couldn't you do the same with more simple parallel-ports
adapters, such as i2c-philips-par, i2c-elv or i2c-velleman? These have
been ported to Linux 2.6 already, and are supported by my unified driver
too, while i2c-pport hasn't been ported and isn't part of the unified

Actually I wonder if I will port and/or integrate the i2c-pport logic in
Linux 2.6, because in most cases, the additional complexity shouldn't be
required. But if you really need it, I'll think of it.
