[SOLVED] broadcom-wl stopped working; now module won't load

I have broadcom 4331 in an old apple macbook pro; the wireless has been working for about a year.

Recent updates to the kernel have caused my broadcom-wl wireless to stop working.

I managed to get  kernel 6.2.6 onto the laptop but now it seems I have an issue relating to loading the broadcom-wl module.

I dont' know why the broadcom-wl module is not available?

I'm not using broadcom-wl-dkms

Any guidance would be much appreciated.  Some information below:  a snippet of the boot log is at the bottom.  Most of this information points to broadcom-wl not being loaded.  How to get it loaded?
