Hi Benjamin,
I just tried an installation using the latest daily sid_d-i netinst image[1]

It failed.  The last few lines of the syslog are:

I'll upload the full install logs (and /target/etc/fstab and 
/target/etc/yaboot.conf) to this bugreport #580455.  But I won't fill up 
your mailbox by attaching it here.

I suspect that Joseph's Jezak's re-write of ofpath will fix this...
