Interesting, I thought fb=false was also required for amiga. I suppose 
that got fixed.

I guess we're going to need to figure out that FPE.

I would say yes. The etch release media wasn't tested (by me) after the
etch-m68k release (where the distribution name got changed). The daily
installer with suite etch-m68k is the best tested combination of d-i
since before etch released. (I just haven't done it lately.)

You need to add suite=etch-m68k and modules=etch-support on the kernel
command line to get etch, see also
(Okay, I haven't verified that modules=etch-support is the correct
solution yet, but it sounds right.)

Unfortunately, none of this gets your past the FPE.

I haven't figured out what package generates the "Detecting hardware to 
find drives" screen. I'd like to see what it's doing when the FPE gets
