That is what I am trying, however when the kernel tries to mount the root
file system, it is unable to find the CF card. And this is the part which
I cannot believe that it can't be fixed.
I still believe that it might have to do with the CF card being marked as
"removable" and the way udev handles these devices, however I don't have a
"fixed" card at hand to verify this. In fact I am not even sure that it is
"removable"; thunar shows it as removable device, however udevadm info
says ATTR{removable}=="0" . Hmmm...

Does not work, because grub does not find the CF card.

The CF slot is actualy pcmcia, not USB.

Yes, the latest BIOS is installed.

This looks interesting, I will have a closer look at it and see if there
is something I can try, one of these days. At a quick glance it looks
like they needed to patch the initrd's init script, maybe I could try to
adapt this.

Basically the same as when being called from the running system, except
that the "SD Host Controller" appears as "System Hardware".
> What is the output from:-

More than fits on the screen, is there something particular I should look
for?
Thanks and regards
