Thank you very much for this explanation, Jaime. My setup is
identical to yours.

This solved the problem. My initial trials included references to
apm and acpi:

,----[ test 1 with menu.lst ]
| root=/dev/hda2 ro acpi=off apm=on nolapic quiet splash resume=/dev/hda3
`----

,----[ test 2 with menu.lst ]
| root=/dev/hda2 ro acpi=on quiet splash resume=/dev/hda3
`----

Using "nosplash" and dropping the keys "apm=on|off" and
"acpi=on|off" as you suggest:

,----[ working menu.lst ]
| root=/dev/hda2 ro quiet nosplash resume=/dev/hda3
`----

leaves me with a working setup. I can now suspend and hibernate
(i) using function keys and (ii) the Gnome System->Quit dialog
entry.

Again, thank you very much!
