Subject:   Lots of Giant locked in dmesg from FreeBSD 13 on a 32-bit laptop

Hello!
I tried to install FreeBSD 13.0-RELEASE on an old 32-bit laptop. After
installing drm-kmod and gpu-firmware-kmod, I am not able to run `sysctl
-d hw.i915kms' (it states `unknow oid') and I can't find any i915kms.ko
file nor in /boot/modules, neither in /boot/kernel.

Here are some relevant lines from dmesg(8):

The video currently is at a very poor resolution (640x480 maybe, or
800x600). Keyboard seems to work.

Does this mean that I won't be able to use any video driver, because these
devices (in particular, the video ones) are no more supported by FreeBSD?

If not, is there something else I can do?

Thank you anyway!

Rocky
