The Shuttle EPAT chip doesn't support ECP, only EPP. Using ECP+EPP mode
rarely works as a perfect substitute for using either ECP or EPP alone. I
vaguely remember reading something somewhere to the effect that the two modes
don't mix well on the same hardware and as such, negotiation tends to fail,
particularly if it's EPP that you want.

You could try setting the port delay to 0 - I found that this improved my
options pd drive0=0x378,,,5,,,0,0 drive1=0x378,,,5,,,0,1
Make sure you test it well afterwards though; it might toast your filesystem
or something if your hardware doesn't like working at this speed.

Try a kernel commandline like:
with x=0 if your system works with delay 0 or x=1 otherwise.
