installaing php4-odbc wants to replace kernel?

[kenn <kenn@printussery.com>]

I've just finished installing freetds and now need to get it to work
with PHP4 ... when I try to install php4-odbc via dselect, here's what I
get:


The following packages will be REMOVED:
  kernel-image-2.6.8-2-386
The following NEW packages will be installed:
  php4-odbc

  You are running a kernel (version 2.6.8-2-386) and attempting to remove
  the same version. This is a potentially disastrous action. Not only
  will /boot/vmlinuz-2.6.8-2-386 be removed, making it impossible to boot
  it, (you will have to take action to change your boot loader to boot
  a new kernel), it will also remove all modules under the directory
  /lib/modules/2.6.8-2-386. Just having a copy of the kernel image is not
  enough, you will have to replace the modules too.

    I repeat, this is very dangerous. If at all in doubt, answer
    no. If you know exactly what you are doing, and are prepared to
    hose your system, then answer Yes.

---------------------------------------------------------
Why does it need to remove the kernel?  and how do i get around it?
/etc/apt/sources.lst looks like this:

deb ftp://mirrors.kernel.org/debian/ stable main
deb-src ftp://mirrors.kernel.org/debian/ stable main
deb http://security.debian.org/ stable/updates main


I know I'm in way over my head, but can someone help me understand this
and what I'm doing wrong?

Thanks in advance.
