Oops, the patch above should instead be:

Index: sys/isa/vga_isa.c
===================================================================
--- sys/isa/vga_isa.c   (revision 238266)

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