Yeah, it's checking to see if you have anything connected to the TV output. To do that, it needs to temporarily unplug the VGA.
You can avoid this by ignoring the TV output
Section "Monitor" Identifier "TV" Option "Ignore" "True" EndSection
Section "Device" ... Option "monitor-TV" "TV" EndSection
If your machine cannot ever have a TV adapter (even with a docking station), we can add a quirk to the driver to never look at the TV output. That requires the pci subsystem values (from lspci -n -v) to plug into the quirk table.
