I haven't used my slackware-laptop (StinkBad T42) for a while, and I thought it'd be a gfood idea to bring it up to date, so I gave 'slackpkg update' and then 'slackpkg upgrade-all'.
It asked me to run Lilo, and I let it. Then an error occurred, and the machine doesn't boot anymore. The boot complains about non-pae processor and tells me to use an appropriate kernel.

I have used a non-pae kernel, and the upgrade installed a pae-kernel.
The processor does support PAE, but doesn't have the flag.

What should I do to fix the system?

Did you edit the /etc/lilo.conf before you ran lilo? Also do you use the huge or generic kernel? if you use the generic kernel you need to update your initrd.gz.

I wonder if it's enough to "re-link" vmlinuz to vmlinuz-huge-3.10.103 and run 'lilo'?
And if so, should I 'chroot' to the '/' of the slackware first?
(I'm now booting Puppy from a USB stick.)

It seemed to be enough to first boot from another device (I booted Puppy from a USB-stick), then
'rm vmlinuz' then 'ln -s vmlinuz-huge-3.10.103' then 'chroot /dev/sda1' and then 'liloconfig' with all defaults.

My Slackware is up and running again!

I wonder If I should update config and System.map as well? And maybe something else?

Well, screen saver hangs...

I guess the screensaver is a problem of its own. This problem seems to be solved.

The screensaver freezing seems to have been "transient". After reboot no such problems. :-)
