That is really strange. At least a corresponding driver entry
should appear, even if the device itself is "dead" (no reaction
when being touched).

This sounds really strange...
On my Lenovo R61i laptop, the touchpad and the TrackPoint
(the "nub") are conbined into the same device, i. e., they
usually act in parallel. They then appear as _one_ device:
a PS/2 mouse.
Example from dmesg:
atkbdc0: <Keyboard controller (i8042)> port 0x60,0x64 irq 1 on acpi0
atkbd0: <AT Keyboard> irq 1 on atkbdc0
kbd0 at atkbd0
psm0: <PS/2 Mouse> irq 12 on atkbdc0 <---
psm0: [GIANT-LOCKED] <---
psm0: model Generic PS/2 mouse, device ID 0 <---
The CMOS setup allows the following configuration that can
disable the stupid touchpad, but leave the TrackPoint:
TrackPoint [ Automatic* / Disabled ]
Touch Pad [ Automatic / Disabled* ]
Now the one psm0 device only represents the TrackPoint, while
the touchpad can serve as a coffee cup warmer. :-)

No. You should check:
# dmesg | grep psm
# dmesg | grep ums
# usbconfig list
to check for USB device entries explicitely (because modern
laptops sometimes utilize an "internal USB mouse" for the
touchpad rather than a PS/2-style device).
No matter how the manufacturer implemented the touchpad
device, it should appear in dmesg.
By the way, is there a /boot/kernel/acpi_<something>.ko
related to your hardware? If yes, try to load it - it might
enable "hidden hardware" that won't show up normally.
Also check if you have a "Synaptics Touchpad":
Again, this assumes that some device entry is already present
for the touchpad (usually psm).
