Can both of you show the output of `devinfo -v` from your systems?

I was able to solve my suspend/resume issue with my nvidia-equipped
notebook by forcing the module load ordering of vgapm in
sys/isa/vga_isa.c:

Index: sys/isa/vga_isa.c

-DRIVER_MODULE(vgapm, vgapci, vgapm_driver, vgapm_devclass, 0, 0);
+DRIVER_MODULE(vgapm, vgapci, vgapm_driver, vgapm_devclass, 0, SI_ORDER_ANY);


The system requires however that I load the nvidia module in
/boot/loader.conf (as opposed to loading it after system is up and
running).
