Sometimes, the solution is:

chvt 1
killall -STOP X
[whatever else you want to do]
[suspend]
[resume]
killall -CONT X
chvt 7


That said, the suspend script which I had working beautifully on my A22p 
has suddenly broken completely - it crashes X on resume, and I don't 
know why. I "haven't changed anything" since it last worked.
