Just wonder if Laptop / Notebook with 3dfx card exist !
I did not see one like this, but there are a lots with ATI Rage chip, so that is possible to find some also with 3dfx chip !

The analog loop signal thing must have been why they skipped voodooz on a laptop. Even on my 486 toshiba vga gets digitally connected with the vga onboard and so is all other I had and seen. Only 3k series and later could be placed on a lap, but they were not power efficient vga chips to be considered worth integrating on a mobile computer where the autonomy factor comes in.
