Updating to
raspberrypi-firmware-20130116-1-any.pkg.tar.xz and
linux-raspberrypi-3.6.11-4-armv6h.pkg.tar.xz
totally broke my PI. The kernel did not boot at all.
I manually copied the old kernel image to my SD card and
after that the machine booted again, but with no LVM so
I was still missing my /var which is on LVM on a separate HDD.

Mounted the SD and the disk on my desktop and untarred
linux-raspberrypi-3.6.11-3-armv6h.pkg.tar.xz and
raspberrypi-firmware-20130110-1-any.pkg.tar.xz
onto them, and now the system works again.
