I've tried every -rc and -mm since, and it cannot resume. (I get no video on resume, even with 2.6.9-rc4, until X resumes, so I get no information what-so-ever, just a dead box. That's why I haven't reported this before.) I have a Dell Inspiron 8600 (Centrino) with the nvidia card. 2.6.9-rc4 suspends and resumes fine, both to memory and disk. Since then, nothing has resumed from suspend-to-ram, but occasional versions (such as 10-rc3-mm1) resumes from suspend-to-disk. I can give any information that people want.
