Bug#359613: reproduced with 2.6.16-1-k7

[Ken Wahl <kwahl@nc.rr.com>]

Same experience with error in line 55 of
/usr/sbin/mkinitramfs-kpkg on up-to-date Sid system

Relevant output from apt-get dist-upgrade:

-------------------------------------------
Setting up linux-image-2.6.16-1-k7 (2.6.16-3) ...

 Hmm. The package shipped with a symbolic link
 /lib/modules/2.6.16-1-k7/source
 However, I can not read it: No such file or directory
 Therefore, I am deleting /lib/modules/2.6.16-1-k7/source

Running depmod.
