Debian's linux-image version 2.6.32-trunk-5 is an outdated snapshot from
when squeeze was testing/unstable: please use linux-image-2.6.32-5-x for
an appropriate value of x. (At the time I write this, the current version
is 2.6.32-38.)

Due to a quirk of how the version numbers are sorted, 2.6.32-trunk-5 will
appear to be newer than any "release" version if you still have it installed,
so Grub will choose it by default.

Are you using init=/bin/sh or "single" (runlevel 1) or something? Those
should be created by the dbus init script, which will normally run in
runlevels 2 to 5 only.

dbus doesn't do anything "advanced" in its interaction with the kernel,
so I'd be somewhat surprised if the kernel you boot into makes a difference...
but please try with a stable release kernel before going further.
