The last kernel I tried was 2.6.21-rc4 and it has the problem; I'll pull the most recent one and give it a try.
Just tested and sound works fine after resuming a 2.6.21 kernel. I just manually suspended my thinkpad twice. The first time with /sys/power/disk set to 'shutdown' and the second with it set to 'platform'. In both cases I got sound after resuming. IOW, the problem seems to be fixed. Since I'd like to get this fix into Ubuntu's kernel, I guess I'll have to play with git bisect some more. I'd appreciate any hints as to what revision could have fixed this. I know for sure that it wasn't fixed on 2.6.21-rc4 but it's fixed in 2.6.21.
