Sometimes it helps to use mkinitrd.yaird to build the initrd (instead of
the default mkinitrd). You can try to install the package "yaird" and
put the following line in /etc/kernel-img.conf:

ramdisk = /usr/sbin/mkinitrd.yaird

(see "man mkinitrd.yaird")

Then do a dpkg-reconfigure of your linux-image-2.6.15-xxx and see if
that gives you a working initrd.
