How do you know?  ;)

In fact, if only I get a night or three to dive into it, the driver LKM can
go beta in a few weeks. A redesign of vital parts appears to have squashed
a nasty bug. I'm still unquiet, though: I prefer bugs leaving a mark on my
hands so I _know_ I hit them. That one disappeared silently instead.

Ahh, Linux Propaganda...

What they do have in Linux/mac68k is a driver framework that can probe the
IWM and eject the disk, and a long way to go to a "working floppy disk
driver", and a clueless webmaster... 'nuff said.

Where'd you get that from? I suppose that - like apparently much of the
other hardware - it cannot be very different from the chip used in the
PowerMacs. And at least Linux/pmac appears to have a floppy driver. So,
there must be _some_ documentation floating around.
