Hey gramster,
I've installed Debian 3.0 on 3 i-openers now and they work fine. Using an IDE laptop adapter I install the laptop hard drive in my normal PC, install Debian from CD and then recompile the latest kernel. Move the drive into the i-opener, turn it on and it runs fine. Most linux users will want to recompile a newer/latest kernel anyways. Its also fairly simple and I'd recommend it. Here is a quick run down of what I do..
Install Debian 3.0 then download and copy linux-2.4.18.tar.gz (this is the kernal I last used) to /usr/src/.
Run 'tar zxvf linux-2.4.18.tar.gz' to extract archive giving you a linux-2.4.18 directory.
Create a link called linux which points to the linux-2.4.18 dir. This is a personal thing I do and is not required but many others will also do this.
Enter the 'linux' directory and do the following...
make config or make menuconfig or make xconfig (I use 'make menuconfig' from console not from KDE or any other window manager)
make dep ; make clean
make zImage or make bzImage (I use 'make bzImage' but the choice is yours. The bzImage in simply compressed more.)
make modules (I tend to not use modules unless required but its a preferance. I still run this though out of habit.)
make modules_install
# backup old kernel
mv /boot/bzImage /boot/bzImage_20030304_01
cp /usr/src/linux/arch/i386/boot/bzImage /boot
link /vmlinuz to /boot/bzImage
link /vmlinuz2 to /boot/bzImage_20030304_01
mv /boot/System.map-x.x.x /boot/System.map-x.x.x_20030304_01 (x.x.x is the kernel version)
cp /usr/src/linux/System.map /boot/System.map-x.x.x (again... x.x.x is the kernel version)
Modify lilo.conf to provide another tag allowing you to boot from the new kernel but also the old one.
Run 'lilo'
Reboot
I think thats pretty much what I do. There are other ways and some people feel strongly that on a Debian system you should use the Debian packages which will build a kernel package. I follow the above guide and it always works fine. Let me know if you have any questions. Have fun!
