What exactly do you see when it fails?

This may be related to a problem I have:

Somewhere between circa 2.6.25.3 (plus then-current
thinkpad-acpi+TuxOnIce+linux_phc) and 2.6.25.13 (plus similar),
suspend-to-RAM stopped working reliably on my T43. Specifically, about
1 time out of 4, resume from RAM hangs at a very early stage (the HDD
LED never turns up and nothing shows on screen except the textmode
cursor). I *think* it happens only when X was running at suspend time.
Hibernation worked fine the couple of times I used it.

I don't have clean version data or bisection yet (this is tricky since
hang is not deterministic).
