Hmm, or some other hardware... I ve seen machines where video ram was
not refreshed. If that piece of hw is critical enough, it will break
resume.

You could try with minimal system, with as little drivers as
possible... use acpi_sleep=s3_beep to determine where it fails.
I don't have ready access to 2.6.26, but with 2.6.24 s3_beep produces
a (endless, loud) tone if I resume immediately after suspend, and
nothing at all if I wait 10 seconds first.
Hmm, okay, that confirms your theory :-(. Contacting BIOS vendor and
looking in DSDT for something strange turning off autorefresh is
something you could try...
