udev *does* recognize (some?) Palm devices.  I've got a PalmOS-based Garmin
iQue syncing fine -- it would be really bizarre if the (relatively rare)
Garmin device was recognized by udev, but the T3 wasn't...

Are you sure the visor and usbserial modules are available to the kernel?
Try 'modprobe visor' as root and see if you can manually load the modules
(both visor and usbserial should show up when you then run 'lsmod | grep
visor').  If not, then it's a problem with the debian linux-image-2.6.15-1-k7
package or a dependent, not udev (or hotplug).  From the bit below, I
suspect a kernel/module issue.

Works for me under unstable (udev only, homebuilt non-initramfs version of the
kernel).  Note I'm running a slightly older version of udev -- it's possible
something broke in the current version.

hotplug: Installed: (none)
udev:    Installed: 0.091-2 (a little older than the current unstable vers.)
kernel:  (home-built)
  these modules are auto-loaded when I invoke a hot-sync on the cradle/palm:
    visor, usbserial

The relevant udev rules are stored in /etc/udev/rules.d/udev.rules (which
is a symlink to /etc/udev/udev.rules):
    BUS=="usb", KERNEL=="ttyUSB*", \
        SYSFS{product}=="Palm Handheld*|Handspring Visor", \
AFAICT this is a stock install of udev.
