Urgh - sorry for not mentioning the kernel version.  I originally tested
with kernel-2.6.5-1.356.  I just tried kernel-2.6.5-1.358.  The
behaviour is exactly the same.

Looks like the graphics adapter is not properly re-initialised during
resuming.  Does this work for others with a i8xx chipset or is it maybe
just a problem with my video BIOS?  I append what X has to say about my
BIOS during initialisation.  Could the last message about "VBE Restore
workaround: enabled." be relevant - although this probably only relates
to virtual console switching.  The machine is a Fujitsu S6130.
