For some reason, the beta2 kernel lost /sys/power/disk on this laptop. That is sad. But it shouldn't break suspend. Removing the line [ -f /sys/power/disk ] || exit 1 from /usr/sbin/pm-suspend makes suspend work again.
What kind of installation did you make? I've seen this problem with some of the Zen installations/kernels i've done, and this seems to be intentional that on Zen kernels some of the /sys/power/ things are missing. Other than that i agree, for a suspend to ram /sys/power/disk shouldn't be required. Read ya, Phil
This was the PAE kernel, not xen.
