installing new kernel

["Jean Monnat" <jmonnat@balcab.ch>]

Dear Debian specialists,

Because of printing problems, I tried to upgrade the kernel
2.4.18-newpowermac to the kernel 2.4.20-ben10. So I downloaded it and then
tar -xvzf 2.4.20-ben10.tar.gz. I followed instructions on how to install it,
that's to say
mv vmlinux /boot
mv System.map /boot
mv modules /lib/modules/VERSION

I changed the yaboot.conf line image=/boot/vmlinux

When I reboot i get this line of message "unable to locate
/lib/modules/2.4.20-ben10..." something like that.
However, when I do uname -a, I can see that the new kernel has been loaded.

Ok, then I tried to configure my USB printer EPSON Stylus Photo 870 with
KDE, and I can see and choose usb dev/lpO. I made a test print, but nothing
happens and I get the message "lpr executable could not be found in your
path, check your installation".
My question is: Do you think that there is any relation between the two
messages.

I do not know if I am clear enough. Anyway thank you very much for your
help.

A lost newbie
