I've played around with this a bit and merged some of the new-mkinit 
into mkinitramfs, at the same time redid the switches (hope you don't 
mind ;-))

Here is the (long) summary:

mkinitramfs basically uses 3 different methods:

--with-modules=<list>  where list is a comma seperated list of modules
--with-file=<file>  where the file is list of modules (one per line)
--all-modules  throw all of /lib/modules/${KVER}/kernel into ipcoprd.img

The installer sticks to method 2 (as before). On my main textbox this 
creates a 1.3 MB image, using all modules makes that into 7.something

To change the ipcoprd.img, switch to console 2 when the installer asks 
whether to restore, and type something like:
chroot /harddisk /sbin/mkinitramfs --with-kernel=2.6.24 --all-modules

or (after extending /harddisk/tmp/module-list):
chroot /harddisk /sbin/mkinitramfs --with-kernel=2.6.24 
--with-list=/tmp/module-list


The thing is that using all modules does not work, since 
/etc/modules.conf is empty and udevd is either not started correctly, at 
the wrong time or has some other problem.

Anyways, it should be lots easier to try and figure out why some boxes 
won't install correctly. For the record, I (only) have 4 different 
machines, which all install perfectly.
