On 8 (.1 and .2) I only had to leave uhci, ohci and ehci (not usb) out 
of kernel and load / unload those around suspend/resume, but that's no 
longer needed on 9 here.

Likely not very exciting news for most, but my '02 Thinkpad T23 reliably 
suspends and resumes since 9.1-R with zero configuration.  Haven't tried 
it yet with X, might need hw.syscons.sc_no_suspend_vtswitch=1 for that 
as 6.x, 7.x and 8.x always required, but that's an old S3 Savage video, 
with working IBM-written ACPI/BIOS.

More modern video chips and drivers seem to be far more problematic, not 
to mention slightly dodgy ACPI code ..

cheers, Ian
