This is not a duplicate of https://defect.opensolaris.org/bz/show_bug.cgi?id=17093.
The workaround is correct, but it won't help for 17093.
I observed this problem on my T61p. Using the workaround, my system is able to suspend and resume, but the USB ports are dead after resume.
Looking at the code for "6867140 ultra 27 does not resume from either mouse or keyboard event" which introduced this bug, I found that it enabled all PCI devices for wakeup, even those that don't support power management. Although I haven't worked with power management stuff before, I think this is wrong. Changing this fixes the resume problem on my T61p, but I don't have an ultra 27 to test it there.
I have been running oi_148 with using the attached diff for about a month now, without any resume or USB problems.
I also uploaded a webrev to http://cr.illumos.org/view/5ihk5w10/illumos-506-webrev/.
