io-graphics provides the “-a” argument to pass argument to the
hardware driver. However I couldn’t figure out where to access
this argument from within the driver.
I discovered, by chances, the igs5000 uses an environment variable
to controle the TV out capability (this needs to be documented somewhere).
That seems to coloborate the fact that -a isn’t fully supported?
I added CRT/LCD selection to the chips_hiqv driver and would like
to avoid environment variables (which sucks IMHO).
