Would users normally expect a debian kernel to include serial console support? (I mean built-in, not modular, so that you can pass "console=ttyS0" on the kernel command line to see what the kernel gets up to.) If so, some options are needed in the mac kernel config-- CONFIG_SERIAL_PMACZILOG=y CONFIG_SERIAL_PMACZILOG_TTYS=y CONFIG_SERIAL_PMACZILOG_CONSOLE=y > > > My first boot attempt wasn't very successful -- my powerbook switches > > itself off after the kernel logs this: Trying to unpack rootfs image > > as initramfs... > > > > I'm sure I have seen powerbooks do this before.

Weird. It is wierd, but I think that the powerbook PMU chip will respond to certain CPU exceptions this way. I've seen powerbooks respond to initramfs like this before but I don't think I ever found out why. But it seems that I have an old kernel binary with a built-in initramfs that works. Another thing to add to the list bugs to investigate... Anyway, your initramfs files work fine on my quadra 650.
