...well, I only made up my mind base on the label "autodetect", but anyway...

Up to now the ftape package seems to have problems with interacting
with parport / parport_pc, so I am forced to leave parport / parport_pc
removable from the kernel. This has already been asked in linux-tape,
but nobody has managed to use ftape working together with parport - so far.

Here it is:
Right after rebooting:
mount /dev/sda4
parport0: PC-style at 0x378, irq 7 [SPP,ECP,ECPEPP,ECPPS2]
ppa: Version 2.05 (for Linux 2.2.x)

mount /dev/sda4
mount: /dev/sda4 is not a valid block device
Absolutely no additional message in dmesg (/var/log/messages)
[ playing around in /etc/conf.modules,
but without any success and any message in dmesg]
modprobe ppa
bpck module successfully unloaded.
[057] zftape-init.c (cleanup_module) - successful.
zftape successfully unloaded.
ftape: unloaded.
parport0: PC-style at 0x378, irq 7 [SPP,ECP,ECPEPP,ECPPS2]

sda: Write Protect is off
sda: sda4
mount /dev/sda4
ls -al /zip4
and so on...
Results: Except for immediately after having rebooted an automatic
loading of the module ppa keeps not possible, whereas a manual
modprobe ppa does work. Workaround: sd_mod to be a module...
But this is not really satisfactory if you think of normal users
who should be able to mount /dev/sda4 (users in /etc/fstab),
because modprobe is reserved for root.
Cheers, Juergen.
