We have only the prep kernels, what target for kernel_building are you using ?
mkvmlinuz knows how to create prep zImages only, so i guess that for those we
need to add support for a ppcbug arch in mkvmlinuz. For this, we need two
things from you :
1) a reliable way to autodetect a ppcbug ppc box. mostly done by probing
/proc/cpuinfo for the other subarches, but i somehow feel that machine will
show up as prep.
2) information on what code path is traveled in arch/ppc/boot/simple to
create the ppcbug image in the 2.6.8 kernel
Just look at the mkvmlinuz script, and the arch/ppc/boot/simple makefile for
inspiration.

You need to use the sym53c8xx_2 driver, which is available, please fill a bug
report against the ddetect package, giving your lspci output (both normal and
with -n), as well as telling you are running a 2.6 kernel.

Well, since this is a netboot image, those should be pulled in by the second
hardware detection phase once net is configured. Please put this info in the
bug report.

you can just go back in one of the menu questions, but you can also boot with
DEBCONF_PRIORITY=medium or low. Not sure if prep allows for command line
arguments when netbooting though, i can simply say :
ok> boot net vmlinuz-chrp.initrd DEBCONF_PRIORITY=medium
on my pegasos.
