Fedora :: F14 On Laptop Mysteriously Stopped Booting?

Fedora 14 on my laptop has randomly decided that it hates me. The system stops booting after "starting atd", right when its starting X. It "hangs" after the fedora logo, though it will reboot when I try "ctrl-alt-delete". I can see that haldaemon is failing to start, and when I boot the kernel with "selinux=0" it gives me an error message:

error while loading shared libraries: libdbus-glib-1.so.2: cannot open shared object file: No such file or directory. NetworkManager fails with same message. the .so file is in its proper directory, where it has been all along. I've tried booting into runlevels 2 and 3. No luck there either. It'll boot to the login prompt, but as soon as I under my userid the screen flashes. I managed to get the error message it was giving me before the flash: inconsistency detected by ld.so: dl-open.c: 503: _dl_open: Assertion `_dl_debug_initialize (0, args.nsid)->r_state == RT_CONSISTENT` failed!

I can boot into single user mode just fine. I've checked dmesg and Xorg logs, but I honestly don't know what I'm looking for (and I imagine that those logs would be useless if I boot into runlevel 1, since the error is at higher runlevels. But I can't get the logs for those because the computer just hangs. SSH and networking are never enabled before the hang.)

I'm at a loss here. I use the machine for both school and work [and I have quite a bit of both to do today] and I've been trying to get it to boot normally for hours now. Anyone have any ideas that I could try?
