I use autoloading to load pcd and pg:
alias parport_lowlevel parport_pc
options parport_pc io=0x378 irq=7
options pg drive0=0x378,,,5,1,0 verbose=1
options pcd drive0=0x378,,,5,1,0 verbose=1 nice=1
alias block-major-46 pcd
alias char-major-97 pg
pre-install pcd modprobe epat
pre-install pg modprobe epat
but sometimes, like today, pcd did not autoload correctly.
I could not use /dev/pcd0 - I was getting a message than no CD is
present. After executing "cdrecord -scanbus" that autoloads and
uses pg, both pg and pcd worked fine. The drive, a HP7200e, was
off power before loading any modules (but was powered on before
loading any module). I run kernel 2.2.2, without extra patches.
There seems to be an initialization problem. I attach the subset of
my /var/log/messages that refer to paride messages, where similar
lines that are repeated have been omitted (I have the full file, if
you need more information).
thanks
