Several ways:

a) You can redirect the console as Bruce mentions

b) there is an option you can add to the kernel commandline to disable
psplash (psplash=false)

c) you can switch the console as you normally would under Linux which
triggers psplash to terminate (Something like Crtl+Alt+F2 then Ctrl+Alt
+F1 again but I can't remember the exact combination off the top of my
head)
