I forgot to revert the usb patch.
Current status:
2.6.29-rc2 +
reverted e39ad415ac15116df213dfa2aa2a4f1b0857af9c (cpumask: use work_on_cpu in
acpi-cpufreq.c for read_measured_perf_ctrs) +
reverted a0d4922da2e4ccb0973095d8d29f36f6b1b5f703 (USB: fix up suspend and
resume for PCI host controllers)

has a working suspend to ram on my T61p. With any of these two patches not
reverted resume hangs.
