drm/vc4: module dysfunctional on Raspberry Pi 3B as of 5.18.0

I for one am having two issues here.

The harmless one is that I'm lacking a cooler for the RPi and my cross 
compiling skills have become a bit rusty.
Both could be fixed quickly, of course.

The not so harmless one is that kernel 5.18.x is completely unusable due 
to an other regression: the SD card is slow to a degree that makes it 
rather unusable, rather simple tasks are tainting the kernel because of 
this. E. g. a simple kernel update takes half an hour on 5.18.x.
Neither sure what's the culprit here nor how to deal with it.

Nonetheless:
Could the module be installed without updating the kernel as a whole, e. 
g.by DKMS?
Is there a way to narrow down the commits in question, e. g. something 
like 'git log ./drivers/gpu/drm/vc4/' in a Git checkout of the kernel 
sources?
