I think you mean 'standby'?

You are hitting something else than missing 4MB pages:
static inline int arch_prepare_suspend(void) { /* If you want to make non-PSE machine work, turn off paging in swsusp_arch_suspend. swsusp_pg_dir should have identity mapping, so it could work... */ if (!cpu_has_pse) { printk(KERN_ERR "PSE is required for swsusp.\n"); return -EPERM; } return 0; }
...so just insert printks into the code to find out what is going on...
