Your assumption about another module being needed is apparently correct
:-)
Without going into it too much, the following seems to get past the
unresolved symbols, the trick is to load the PC architecture module. Now
it just complains about not finding the device or my options (or lack
thereof) so back to your ppa howto.
[root@gripz root]# cd /lib/modules/2.4.9-7/kernel/drivers/parport/
[root@gripz parport]# ls
parport_cs.o parport.o parport_pc.o parport_serial.o
[root@gripz parport]# pwd
/lib/modules/2.4.9-7/kernel/drivers/parport
[root@gripz parport]# modprobe parport
[root@gripz parport]# modprobe parport_pc
[root@gripz parport]# modprobe ppa
/lib/modules/2.4.7-10/kernel/drivers/scsi/ppa.o: init_module: No such
device
Hint: insmod errors can be caused by incorrect module parameters,
including invalid IO or IRQ parameters
/lib/modules/2.4.7-10/kernel/drivers/scsi/ppa.o: insmod
/lib/modules/2.4.7-10/kernel/drivers/scsi/ppa.o failed
/lib/modules/2.4.7-10/kernel/drivers/scsi/ppa.o: insmod ppa failed
