[PATCH 3/4] suspend: Documentation update for IBM Thinkpad X30

["Antonino A. Daplas" <adaplas@gmail.com>]

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.
