 I'm not sure if this is going to help, but some of the FIC Athlon boards
wouldn't work at all, if they didn't have a certain power supply
(certified by AMD), and some other boards (like the Asus Athlon board)
would cause a TNTUltra to die horribly without said power supply. Some
of them just don't provide enough beef in the right area. 

 That *could* be the problem. Read through the Athlon motherboard revies
on www.arstechnica.com & make your own mind up as to whether I'm useful or
not :) They link an AMD sponsored site that lists what PSUs are good.

 Alas, the regulator is a bunch of capacitors & inductance coils on the
motherboard, that smooths power to the CPUs. I can't see why a type of
regulator would mess up a video card, unless it drew too much power from
the rest of the board.
