I've probably had the most persistent problems with red-screen.  I seem 
to remember that for me it took a complete power disconnection to clean 
up.  A regular power-down still leaves power to some parts of the 
system, and I had to either unplug or flip the switch on the back of 
the power supply.

But sometime around last summer I moved to a new kernel the the red-
screen problems went away.  I don't know exactly what kernel fixed it, 
but I see that a config dated Aug 15, 2010 was 2.6.35-gentoo-r1, and I 
don't appear to have moved to a 2.6.36 series kernel until late 
December.  I'm guessing that 2.6.35+ fixed it, for me.
