Following Kees's remarks, I removed the --baud option from inputattach
udev rule. After having commented out the wacom xorg.conf snippet, I
restarted X, and now the wacom tablet is properly working with the evdev
driver. I see now the following in my Xorg.0.log:

Thank you very much for your help. Since the --baud option seems
problematic for the X200 series, and since according to #616443, Fujitsu
models work with the --baud option, maybe the udev has to be split?
SUBSYSTEM=="tty", KERNEL=="ttyS[0-9]*", ATTRS{id}=="FUJ02e5",
ACTION=="add|change", RUN+="/lib/udev/inputattach --daemon --baud 19200 --w8001
/dev/%k"
SUBSYSTEM=="tty", KERNEL=="ttyS[0-9]*", ATTRS{id}=="WACf00c",
ACTION=="add|change", RUN+="/lib/udev/inputattach --daemon --w8001 /dev/%k"
Maybe some text can be added to README.Debian to document the fact that
once the tablets are attached, one can use the evdev driver instead of
wacom? Something like:
This package includes a udev rule to automatically attach Wacom W8001
devices on Fujitsu T2010 or Lenovo X200-series laptops and tablets. Once
attached, these devices will be supported by the evdev driver with X.org.
In that case, ensure that the wacom driver does not interfere.
