I don't understand why parport_pc isn't there; try "modprobe
partport_pc".  If that works, then "modprobe ppa".  If they don't
work, use the "insmod /path/to/modules/partport_pc.o" versions of the
commands.  If that doesn't work, mail us the error messages.

On another matter, check whether /etc/modules.conf (or possibly
/etc/conf.modules) contains the line "alias parport_lowlevel
parport_pc".  If not, that probably explains why parport_pc doesn't
get loaded at boot.  (In fact, I don't understand why you say you had
to insmod; the parport stuff normally gets loaded at boot AFAIK.  I'm
not sure when, my uptime is too long on the box where parport is a
module and the logs have rolled over about elevnty-three times since
boot :-)

(parport_pc is what talks directly to the hardware.  According to the
system there are several other possible lowlevel drivers.  This is why
parport, which cannot talk to the hardware without the help of a
lowlevel driver, doesn't depend on parport_pc---it might not be the
right one for your hardware.  I don't know if it could depend
indirectly through the alias above; but apparently not, probably
there's no interface for an alias---which doesn't actually have any
code to define symbols!---to export symbols so that dependencies could
be determined.  So modprobe doesn't pull it in.)

    Ulrike> Aha?

Well, up to the hash at the end of the name which is used to make
absolutely sure that you can't use the module except with the kernel
it was compiled for.  So that doesn't really tell you anything.

I don't see anything strange in your .config (quick skim, maybe Austin
will find something?).  If the modprobes above don't work, send us the
error messages.
