Isn't the VESA local bus standard limited to 40MHz for plug-in cards? 
(but hard-wired local-bus stuff on the motherboard can go up to 66MHz?)
Wouln't this be a problem in a true 50MHz machine?  In this case a DX280
(if one were ever produced) would be the highest speed you could have without
causing problems.
