While bisecting a dri S3 issue I stumbled in 2.6.38-rc1 over a regression because of NX protection (5bd5a4, currently being discussed), and with a patch fixing this issue I stumbled again in 2.6.38-rc2 because of commit bd924e8: smp: Allow on_each_cpu() to be called while early_boot_irqs_disabled status to init/main.c Reverting this commit makes suspend work on SandyBridge again. I haven't tested reverting this commit on v2.6.38-rc2 yet, though. I'm compiling for i586, not x86_64. lspci -vvv output is attached.
