I've tried them, they didn't hurt... :-)
I've put it this way because after doing more tests I've realized that the
correlation between hald running and the disconnect+reconnect behavior was just
a coincidence.  I am able to reproduce the disconnect+reconnect behavior even
without hald running.  So I guess that this clears hal of suspicions.  Sorry for
the noise.

Hans,

I've put a usbdump file here: http://people.freebsd.org/~avg/kindle.usb.dump.gz
This is is without hald running.
The following system log messages correspond to the dump:
