Got struck with an idea while driving home from work and had to try it..
It's not a crazy performance bump, but for only a few lines of code it's not a bad free performance boost.
For now only applied on the SVGA driver but I should be able to make this global so it effects ET4000 and Mach as well.
There are further optimisations which could be made in the same spirit but requires more work.
Cirrus GD5434 now vs previous driver:
