Two suggestions:

a) If you can, use a serial console.  It is by far the best.
b) You might be able to use options like video= to set a vesafb console 
that will fit most information.
c) Even if you don't have a serial console, you can set a secondary 
serial console with extremely low baudrate, like 300 or 1200 baud.  If 
so, it will slow down console output to the rate that you might be able 
to read it.
