I've had a 9600/300 sitting idle for the last few months, so I decided to install Ubunto 5.10 on to it. The installation went well except near the end.
From what I've read online, you have to copy the kernal and ramdisk to the linux partition by mounting the MacOS partition and copying it by command line before letting it restart and completing the installation. I tried that, but when I went to list the paritions, the ones from MacOS were not there.
This 9600 has an ATTO SCSI card with a 9GB UW SCSI drive attatched and a 4.3GB on the internal SCSI connection (apparently - I'll vcheck when I get home). When the installation was started, the drive on the ATTO was one of the choices that I could install Ubuntu onto.
