Hmm proper IDE driver...
1) I can mount the CF-Card "by hand" and inspect the filesystem. And  
it looks good. I can use the file-system in "near single-user-mode".
2) In my "linuxrc" I do the following to load the modules:
------------------------- [ BEGIN linuxrc ] -------------------------
...
PCIC="ide_cs yenta_socket pcmcia_core pcmcia rsrc_nonstatic"
for Module in $PCIC
do
        modprobe $Module
done
lsmod
...
if [ "$DEBUG" != "" ] ; then
    /bin/sh < /dev/console
fi
...
------------------------- [ END   linuxrc ] -------------------------
Is this indication enough, that I use the  proper IDE driver?

Has the driver (I think "ide_cs"?) which seems to work from the  
initial RAM-disk to be loaded again before the kernel mounts the root- 
fs?
Thanx for any explaination.
