The above wakeup error is gone, and as a result I can switch to use the wpa_supplicant nl80211 driver. With the nl80211 driver everything works. However, with the wpa_supplicant wext driver the issue remains that only the frst ifup after module load works, the second ifup shows the association problem most of the time (but not always). So this turns out to be a mix of two problems, with the wext one not having anything to do with suspend/resume. If you want me to test something wext related, let me know. Otherwise I'm fine with using nl80211.
