suspend: Documentation update for IBM Thinkpad X30

PATCH 3/4 suspend: Documentation update for IBM Thinkpad X30
As reported in Bugzilla Bug 6406, resume from S3 results in a blank screen.
For the IBM Thinkpad X30 using vesafb as the console driver, successful resume from S3 requires option acpi_sleep=s3_bios,s3_mode. Update documentation.
I would presume that, in any hardware, using vesafb as the console driver will require as a minimum s3_mode.

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.

For vgacon, s3_bios may be the only option needed since POSTING automatically goes to text mode. For vesafb, s3_mode, in most cases, will also required.

I'll try, although in-kernel suspend works for me properly.

Please do, we'd really like to use s2ram everywhere (so it "just works"), and we want to know that we are not breaking working setups, too. (Plus whitelist entry can probably be improved).
