Thank you all for your helpful advice and info.

I am giving up on squeeze because I get so many problems with building
a series 3 kernel. I tried to download a kernel image from wheezy, but
got problems when I tried to install the Debian package. I tried
downloading and installing the dependencies, but putting a wheezy
kernel onto a squeeze system did not work. So I have now downloaded
the first DVD iso for wheeze and I shall try to install a series
3 kernel for that release.

Again, thank you all for your help.
