/dev/hda3 on / type ext3 (rw,errors=remount-ro)
/dev/hda1 on /boot type ext2 (rw)

No, I experienced no other issues and /vmlinuz was not replaced by a symlink, 
but I am running the kernel 2.6.26-1-686. I think apt/aptitude changed 
my /boot/grub/menu.lst accordingly. My standard boot entry is:
title           Debian GNU/Linux, kernel 2.6.26-1-686
root            (hd0,0)
kernel          /vmlinuz-2.6.26-1-686 root=/dev/hda3 ro vga=791
initrd          /initrd.img-2.6.26-1-686

So, /vmlinuz is no longer required and after a kernel update apt/aptitude 
changes the /boot/grub/menu.lst  to use the newest kernel as standard.

BTW:  /vmlinuz-2.6.26-1-686 is located on my boot partition:
$ ls -l /boot/vmlinuz-2.6.26-1-686
-rw-r--r-- 1 root root 1506512 Mar 13 17:36 /boot/vmlinuz-2.6.26-1-686
$ ls -l /vmlinuz-2.6.26-1-686
ls: cannot access /vmlinuz-2.6.26-1-686: No such file or directory

The file vmlinuz still exists, was not changed or updated after the upgrade:
$ ls -l /vmlinuz
-rw-r--r-- 1 root root 1505936 Feb 21 15:32 /vmlinuz

Best regards,
