It isn't that vital ;-)  I am more interested in solving the 
problem, than in the solution state.

If I turn this on (SC_NO_VTY_SWITCH), then sometimes my laptop
will start an interrrupt storm on resume, and have no video.
I can type blind for a couple seconds, but then upon the 
attempt to re-initialize the display, it slows very quickly to
nothingness.

DPMS support is enabled, and working.  
'xset -display :0 dpms force off'
works as expected.  Also, the fact that it turns white instead 
of off leads me to believe it may be a mis-guessed register 
location on the radeon 128.  I downloaded a C program called
radeontool to try and find the right registers to use to turn
this off, but cannot find the associated function in the acpi
video handling code.  I am assuming someone else will have way
more intimate knowledge with the kernel codebase than me.

Thank you kindly for your insight, and I will continue to look
for a graceful solution.
