Hi Finn, Yes, actually I have tried an older prebuilt kernel that Laurent made. It was a 2.2.x series kernel, and it did at least get passed the point that my 2.6.x kernel did before kernel panicking later on.
I got curious and dug out my PowerBook 190cs and tried Debians's 2.6.25-2 kernel. I'm pretty sure that I downloaded it here, http://people.debian.org/~smarenka/d-i/m68k/images/daily/kernels/vmlinuz-2.6.25-2-mac There's also http://packages.debian.org/sid/linux-image-2.6.26-1-mac but I've not tried it yet. You can get the .config from the .deb there if you need it. There is no PMU ADB driver configured into Debian kernels, so the PowerBook keyboard didn't work (which is not to say that the keyboard will work if you do configure in the PMU ADB driver...) There's a big warning from the IDE driver, though it still read the partition map from the IDE disk. And there's the bus error from the mac_scsi driver: [ 7.600000] scsi: waiting for bus probes to complete ...

This is an old bug. But I did get macscsi to work -- it even booted to a login prompt -- by powering on the SCSI disk after the kernel had started executing. So the bug is probably nothing too serious. The log from the most successful attempt follows. I don't know if these results are at all applicable to the PB 520, but I'm curious to know what it does. It would be helpful to log the serial port. (A mac printer cable is fine if you are logging on another mac. I use ZTerm and kernel arguments like those below.)
