I use the kernel from linux-image-2.6.12-1-amd64-generic. That one has
initrd and cramfs and such support and all the other options debian
expects a kernel to have, and also what the debian installer expects. I
suspect you don't have initrd or at least not cramfs initrd support and
that makes the installer fail to load the initrd containing the
installer. The initrd also has to be rebuilt for the kernel from the
debian-installer package, and the udeb's rebuilt using another debian
package.

Well if you say the driver appears to work, I would be willing to try
building an image with a _debian_ 2.6.12 kernel with that driver in it.
Starting from kernel.org sources is way to much work.
