resume from suspend fails with 2.6.33-70 update

I have been suspending my 10.04 mythtv workstation for over a year with the command "/usr/bin/dbus-send --print-reply --system --dest=org.freedesktop.UPower /org/freedesktop/UPower org.freedesktop.UPower.Suspend" and resuming by remote control (lirc) with USB0 enabled in /proc/acpi/wakeup. This has worked well from the start and all kernel updates including 2.6.28, .29, .30, .31, and .32. It's only with this latest .33 update that resume fails. Suspend still works but resume fails. Reverting back to .32 in grub allows resume to once again work correctly.
