Not sure this is related with the OP's problem, I have noticed that on my 
system I can scroll up in a console if it displays the output of a command, 
e.g. ls, but I cannot scroll up on the boot messages.  Also, I cannot scroll 
up on the log messages on VT12.  Is there something that I need to set up in 
the kernel?  In the old days (perhaps different machine?) I used to be able to 
scroll up in both.

$ cat /usr/src/linux/.config | grep SCROLLBACK
CONFIG_VGACON_SOFT_SCROLLBACK=y
CONFIG_VGACON_SOFT_SCROLLBACK_SIZE=128
