I guess that this will have to stop working then, because there is no
grub, or lilo installed in the Slackware partition. It's really a shame,
as it's worked so well up until now.

title Slackware 9.1 - slack partition
kernel (hd0,8)/boot/vmlinuz root=/dev/hda9 vga=788 hdb=ide-scsi hdd=ide-scsi

title Slackware 9.1 - slack partition 2.4.22
kernel (hd0,8)/boot/vmlinuz-adaptec.s-2.4.22 root=/dev/hda9 vga=788 hdb=ide-scsi hdd=ide-scsi

[root@fatman boot]# ls -l
total 2752
-rw-r--r-- 1 root root 1404802 Jan 15 2004 vmlinuz
-rw-r--r-- 1 root root 1404802 Jan 15 2004 vmlinuz-adaptec.s-2.4.22
[root@fatman boot]#

You will note a complete lack of a grub directory, and, obviously, any
files therein. No initrd either, as that's the Slack way.

title PCLinuxOS
kernel (hd0,11)/boot/vmlinuz root=/dev/hda12 devfs=mount hdb=ide-scsi hdd=ide-scsi vga=788 splash=verbose show0pts
initrd (hd0,11)/boot/initrd.img

If the above had installed a boot loader, it would have been lilo, but
this grub stanza does the job instead. Contents of the /boot directory
below.

Lots of extra junk it there, but again no grub directory.

Grub needs to be installed exactly once, by one OS. All other additional
OS need only have a stanza added to the single menu.lst used by that
single installation of grub. If there is a separate boot partition, it
will be found in /grub/menu.lst. If there is no boot partition, it will be
found in /boot/grub/menu.lst on the partition of the OS from which grub
was installed.

For Red Hat/Fedora menu.lst will be renamed grub.conf.

As you choose to chainload multiple grub installations, I can see why
you'd be confused about how grub actually works. I have one grub, on a
boot partition, with multiple stanzas for the various OSs, seven at
present, and all boot just fine. If OP has the problem that he states,
there is most probably a syntax error in the Slackware stanza in his
menu.lst.
