Hi,

after having a lot trouble to reproduce the situation described by others,
I was finally able to survive a S3 to get a working console. But I'm still
unable to get the screen on and it stays dark. I tried several permutations
off all found hints, but no success so far.

The System:
linux-2.6.10 + resume-finish-split + pci-resume-2.6.9 + pci-resume-old
vesa:off radeonfb:off (fbcon:on)
xorg-6.8.0-r3 (gentoo, radeon s3 patch included)

I tested with the appended script, with several freezes and always black
screen. MagicSysRq-Boot and PowerOff works most the time, so the kernel
responds. Another observation was, when starting the vesa X11 for the first
time, I can see rests of the Samsung Boot logo, which seems to stay
in memory (maybe a hint for incorrect POST address later by the tools?!).

Like Mathias Hentges wrote, the vesa X11 crashes after resume.
Saving VBE state after vbetool post freezes the machine.

Any hints?!
