Hello,I see the same when I resume from sleep on my 2887 R51 when I touch the keyboard while it's coming up. If I don't touch the keyboard until it is fully up, I have no problems.
BTW, are you sure that ACPI doesn't work? If the screen is blank on resume, try using ACPI but put "acpi_sleep=s3_bios" on the kernel command line. That brings up video correctly on mine.
Greetings, Michael.
