Bug#288812: kernel-image-2.4.27-1-686: upgrade from v2 to v6 breaks nvidia-kernel-2.4.27-1-686

I am sad to say that an attempt to collect more info resulted in me wasting 
about 3 hours without a decent result. For some reason, when I rebooted
into 2.6 (an attempt to avoid the "you need to reboot soon"), and did

dpkg -i kernel-image-2.4.27-1-686_2.4.27-6_i386.deb

the resulting kernel didn't want to boot. During the boot log it complained
about being unable to load sg.o; I looked at the initrd image and found
that sg.o wasn't there indeed. 

So I added a script

/usr/share/initrd-tools/scripts/sg-module, containing the following:
#!/bin/sh
case "$VERSION" in
    2.4.*)
        cp /lib/modules/$VERSION/kernel/drivers/scsi/sg.o \
                $INITRDDIR/lib/modules/$VERSION/kernel/drivers/scsi/
        ;;
esac

and manually re-created the 2.4 initrd. The kernel still refuses to boot,
while no longer complaining about the absent sg.o; the last messages it spits 
out are

pivot_root: No such file or directory
/sbin/init: 425: could not open dev/console: No such file
Kernel panic: Attempted to kill init!

An attempt to downgrade back to -2 did not help this time, the results didn't 
change. Is something broken with my initrd-tools? Was it a stupid idea to do 
it under 2.6 rather than under 2.4 (the previous upgrades of 2.4 were done 
while running 2.4)?

If you have any ideas what to do, I'll be happy to try them out to collect 
further info for you.

So I installed module-assistant, and (under 2.6) did the following:
        module-assistant prepare
        module-assistant auto-install nvidia-kernel-source
and now I have nvidia acceleration working under my 2.6.
Here's the lspci output (collected under 2.6):
