What Lee is trying to do is to call the BIOS to detect if the VESA ID can be found. This should not change the HW state (if we *assume* BIOS is sufficiently sane). It should not be more intrusive than what drivers with ISA probing already do - including the vesa driver. The advantage of such a probing in Probe() would be that the -configure option works. On the other hand of course it would require changes to the int10 system to be able to work without a valid entity.
