It seems that most of the failures people are getting installing rc1 are
because hotplug loads unsafe kernel modules, including hardware
watchdogs, and frame buffer modules that don't work right. It doesn't
help that as you noticed hotplug brings in all these unnecessary modules
even in single user mode.

Your problem sounds like hotplug loading a bad frame buffer module. Try
booting in emergency mode ("linux emergency"), remount the root
filesystem read-write ("mount -o remount,rw /"), remove
/etc/rcS.d/S40hotplug, then you should be able to boot without this
problem. If you can send us your lspci and lspci -n output, we can
probably determine which module hotplug is loading to cause your
problem, and fix it.
