Hi,
Following the thread on getting resume working on the T61[1], I
factory reset my BIOS once more but this time confirmed the modem was
enabled. Resuming then worked fine on 11-CURRENT r270990 AMD64.
hw.acpi.reset_video=1 needs to be set otherwise system resumes without
switching the system back on.

With vt & i915kms, when the system goes to sleep, it reports (trimmed):
pci5: failed to set ACPI power state D2 on \134_SB_.PCI0.PCI1.CDBS:
AE_BAD_PARAMETER
pci0: failed to set ACPI power state D2 on \134_SB_.PCI0.EXP0: AE_BAD_PARAMETER
pci0: failed to set ACPI power state D2 on \134_SB_.PCI0.EXP1: AE_BAD_PARAMETER
acpi0: cleared fixed power button status

and when it wakes, it reports
uhci_interrupt: resume detect
error: [drm:pid786:intel_lvds_enable] *ERROR* timed out waiting for
panel to power off

With sys cons, , when the system goes to sleep, it reports:
pci5: failed to set ACPI power state D2 on \_SB_.PCI0.PCI1.CDBS:
AE_BAD_PARAMETER
pci0: failed to set ACPI power state D2 on \_SB_.PCI0.EXP0: AE_BAD_PARAMETER
pci0: failed to set ACPI power state D2 on \_SB_.PCI0.EXP1: AE_BAD_PARAMETER
acpi0: cleared fixed power button status

I've not had a chance to test X or the USB ports.
