Brought my Thinkpad T23 (actually a replacement, similar model, same HD) 
to '8.1-STABLE #0: Sun Sep 5 15:53:00 EST 2010' but this issue persists, 
as it does if booted from 8.1-i386-memstick, HD present but not mounted; 
this one has the CDRW rather than the original's DVD-ROM, if relevant.

Before excruciating detail of the issue in mobile@ and acpi@ again in 
hope of debugging hints, have you (Ted or anyone) any further news on 
Thinkpad T-series (or other) 60 second stalls/freezes on S3 resume?

[Please read the abovementioned thread before asking any questions]

cheers, Ian
