Did you try : 

  http://people.debian.org/~luther/prep/d-i-2005.01.03-prep

It is the debian kernel with the prep_pci patch, and the debian-installer
(yesterdays or so daily-built) initrd on top of it. I simply boot it from
netboot with :

  boot enet:192.168.1.10,d-i-2005.01.03-prep,192.168.1.17

(where .10 is my tftp server, and .17 a random free address on the subnet).

And it works fine. I plan to do a kernel upload soonishly to fix those issues
in debian, but i would like to have also the fixes for the other prep systems
if needed.
