I believe suspend/resume support has been added recently to bcma. Maybe some additional interfacing between brcmsmac and bcma is missing for that.
Does this problem persist with current rawhide kernels?
It does, there is some progress however. Running 3.2.0-2.fc17.x86_64 after resume I see this: [65721.119134] ieee80211 phy0: wl0: wlc_suspend_mac_and_wait: waited 83000 uS and MI_MACSSPNDD is still not on. [65721.119151] ieee80211 phy0: wl0: psmdebug 0x00ff8f6d, phydebug 0x00000000, psm_brc 0x0000 but now I can at least unload brcmsmac and reload it manually without killing the kernel.

bcma was doing old-style PM ops and did not call the suspend/resume functions for the registered drivers (ie. brcmsmac or b43). Linus dived into it as he wanted bcm43224 in his MacBook Air to work and created a number of patches. Not sure what the status of those patches is as I was unable to test them on my machine over here.
This issue should be resolved with the 3.3-rc2 kernel in rawhide. The patches Linus included are contained in that release. If you are still hitting this with the latest rawhide kernel, please reopen.
