This is because you've failed to follow some of the instructions that
were given to you, please see below:

You must have meant "unresolved symbol", not "symlink".  This suggests
that you did not apply some of the patches from under /usr/src/kernel as
I had suggested in another posting.  In order for you to be able to load
modules into the CD-booted kernel, those modules have to be from a
kernel patched and configured in _exactly_ the same way as the kernel on
the CD.  This means that you must apply all of the patches under
/usr/src/kernel (for Owl 2.0, that's linux-2.4.32-ow1 and
patch-cryptoloop-jari-2.4.32-ow1) _and_ use /boot/.config off the CD
(your enabling the compilation of some drivers as modules must be the
only change).

Well, the name /dev/hdb1 suggests that your system sees this as an IDE
drive, and this low transfer rate is normal for 16-bit PIO mode (this
happens when you have an IDE controller - or one pretending to be IDE -
for which there's no driver in the running kernel).

I am guessing that you had used your newly-built kernel for this
installed system.  So you finally had the kernel and the module match.

Great!

We do not have a "hardware compatibility list", although it might be a
good idea for us to start maintaining one for the next release.

For now, you'll have to refer to the default CD kernel configuration in
/boot/.config to find out what drivers are enabled (without you having
to build/load a module).
