vbetool on pure AMD64 system

Hey guys,

due to your work in new kernels, my AMD64-laptop now resumes after an ACPI S3
suspend (I can type commands and they get executed) :-). Thanks a lot.

But the LCD stays black. So I read about the various options to reinitialize
the VGA, which were:
1. kernel boot options: acpi=s3_sleep, acpi=s3_mode, pci=routeirq. I tried
each one of them, LCD still stays black.
2. Using the vbetool to save/restore the state of the VGA.

Here is the problem: I didn't find an AMD64 version of vbetool (using Debian
testing AMD64), so I forced the i386 package and manually met its 32bit
dependencies. It does run, and the "vgastate off" option does disable the
LCD. But saving and restoring the state, I get the following error:

# vbetool vbestate save > /tmp/save
Can't get video state buffer size (vm86 failure)
Get video state buffer size failed
Can't save video state (vm86 failure)
Save video state failed

So I guess, there is some reason, that this program does not work on 64bit
machines. Is there a workaround or any other idea, how I can get my display
back alive?

Thanks,
Frank
