which vga adapter is in your laptop?
have you tried the the kernel parameters:

        acpi_sleep=     [HW,ACPI] Sleep options
                        Format: { s3_bios, s3_mode }
                        See Documentation/power/video.txt
(see kernel documentation, kernel-parameters)

normally, if you use an 2.6er kernel an your bios isn't too buggy a
should bring you back your display.

For Suspend in general, install the hibernation package..
