I have tried your patch on already installed disk image, and it works
without problem. I tried Debian etch (kernel 2.6.18), etchnhalf (kernel
2.6.24) and lenny (kernel 2.6.26).
I haven't done any change on the qemu side. Given that the mac-io ide is
detected before the CMD646, I have to pass -hdc to the disk image so
that it is recognized as -hda by Linux. I'll do test with the different
install CD tomorrow.
