Well, some hardware just preserves video state, but you are right that
anything that needs s3_bios probably needs s3_mode, too.

Do you think you could try code from suspend.sf.net and fix whitelist
there? It is really wrong to have whitelist in .txt, when it should
have been machine-readable.

(I applied this:

diff --git a/Documentation/power/video.txt
b/Documentation/power/video.txt
index a8004cc..d859faa 100644
--- a/Documentation/power/video.txt
