There's no such directory.
I'm using udev 167-3 and the kernel was linux-image-2.6.38-2-amd64
2.6.38-4 for the latest problems.
Now I'm using linux-image-2.6.38-2-amd64 2.6.38-5. I did a single
reboot and the problem didn't appear.
I don't know whether this is related, but apart from ordering
differences, lsmod shows the following ones: when the bug appeared,
I got
evdev 17475 16
and no joydev module listed. Now (where the bug doesn't appear),
I get
evdev 17475 17
joydev 17138 0

So, the differences are:
When the bug appeared:
[ 15.080771] input: PS/2 ALPS DualPoint TouchPad as /devices/platform/i8042/serio1/input/input13
When it doesn't appear:
[ 10.991351] input: DualPoint Stick as /devices/platform/i8042/serio1/input/input7
[ 11.009085] input: AlpsPS/2 ALPS DualPoint TouchPad as /devices/platform/i8042/serio1/input/input8
Is there any other useful information I can give?
