Pi4b and Pi5 users - What should go in a 2.9.3 image

VNC should not be included with official releases, it is a huge security risk.

It won't be 

7c81 and RPi5 will not work at the current time. The driver needs rewriting and the driver that uses spidev is not suitable.
This situation does not seem to be changing anytime time soon.
The 7c81 product page at Mesa states that the 7c81 will not work with the RPi5.

In regards to "The 7c81 product page at Mesa states that the 7c81 will not work with the RPi5". I was wondering if the Mesa company writes the driver normally or if the missing support for the RPi5 is something that is part of the LinuxCNC 2.9.3 image?

As i understand it, it is a RPI manufacturer issue, most probably hardware side of things, as i doubt if software issue it would have been solved by now.
As far as i recall, there are several versions of RPI5 and back then any new version would be crippled by issues for a long time, plenty of videos on youtube about that.
Chip shortage caused a lot of headaches for all manufacturers, but the way RPI owners handled it, is by far the worst way, ignoring issues and waiting for others to fix the issues while they were busy getting rich from the 180$ price tag.
Same ... well much worse, with Intel, blaming everything and everyone while knowingly selling 400-1100$ processors. Millions of it.
Personally, i blame humans for standing that kind of s#it. I do not, vigorously!

Becasue there is a new chipset  in the 5, there is as yet no known SPI interface. It that becomes available then one of the developers could look at it if they feel like it

There is an spi interface, it works using the kernel module. Unfortunately going by this route is not fast enough for real-time situations.
