so, you are absolutely sure that this happens without nvidia driver?

if not, rename the nvidia kernel module and try again.....

kernel logging should still be there (dmesg), but it may not go to /var/log/messages.
you may start syslogd/klogd manually in that runlevel

The problem is reproducible, as I wrote, also while booting through 
init=/bin/bash parameter(and in init 1, but with hang instead of reboot) 
so before loading any modules or nvidia drivers(but this case leaves no 
logs becouse logging is down too)
I mentioned first and last line as commented, just to ensure that it's 
everything about this symptome(timestamps suggest that)
