Xorg 1.6 + evdev + hal = puzzling keyboard behavior

Dear HAL list
I post here for the first time and unfortunately it is to report a problem
which I think is related to HAL.
I shall first describe my system:
fresh gentoo install with keyword ~amd64
uname -a
Linux wonderland 2.6.30-gentoo-r2 #1 SMP Tue Jul 7 11:54:54 CEST 2009 x86_64
Intel(R) Core(TM) i7 CPU 920 <at> 2.67GHz GenuineIntel GNU/Linux
hald --version
HAL package version: 0.5.12rc1
udevd --version
141
hotplug version: 20040923-r2
X -version
[...]
X.Org X Server 1.6.1.902 (1.6.2 RC 2)
Release Date: 2009-6-29
X Protocol Version 11, Revision 0
Build Operating System: Linux 2.6.30-gentoo-r2 x86_64
***
I shall now describe the problem: in one word, it is impossible to get a
usable keyboard when HAL is running.
When I start X (kde4) it is as if a key was constantly pressed. This key
changes each time. I've got a console which pops up automatically when I log
in, and I see it being filled, for example, with the character '2'.
If I use kdm the problem starts at the login screen, with characters being
repeatedly written in the "login" field. Some random characters are also
displayed. It is not only printable characters, from the behavior I can guess
that, for example, arrow keys are also "pressed".
It happens regardless of the content of xorg.conf (with or without InputDevice
sections, whith either kdb or evdev as a driver, and even with no xorg.conf at
all). I have got evdev built in the kernel and evbug as a module. If I stop
hald and use kdb and mouse as drivers for input devices the problem
disappears.

Here are some helpful files:
relevant section of /var/log/message, striped of all evbug events (hald
was run with "hald --verbose=yes --use-syslog=yes")
http://perso.crans.org/raybaud/messages.hald.gz
I just started hald, then ran startx, then pluged in a usb HDD which kde
failed to notice, then pressed a key (f12), then stoped X, then stoped hald.
the same, including evbug events:

***
Some context:
the install is fresh. Everything used to work fine before I reinstalled the
system (because of hard disk failure. No global configuration file has been
preserved). I didn't do any fancy configuration except the ~amd64 keyword (I
bet I deserve what I get ;) ).
I believe this is a hal-related problem because it also fails to show pluged
external hard drives in kde (the device exists in /dev, but kde doesn't seem
to notice it. I think HAL is supposed to tell him, so I supposed it fails to
do so)
I may rebuild HAL with the "debug" flag turned on if you feel it's necessary,
or run whatever experiment you think may help.
best regards,
