For those old things, I use either:
a Number Nine Ticket to Ride-based Formac card (excellent 2d)
or a Mach 64
or a RAGE-based card (if I've got one sitting around)
but I usually use a Matrox Millenium II. They're good cards, and some of the retail peecee versions are flashable (though I've found that the OE models aren't).
There's really no point in using anything higher than a 32MB RAGE 128, because older Macs can't feed a faster card at a rate high enough to keep up with the card's processing abilities. Besides, if you just want to drive a larger display, more than 32MB is never utilized even if you're driving some immensely huge screen; 16MB is more than adequate for driving 1280x1024@24bpp.
One thought: I wouldn't try using any card longer than 6", as it most likely won't fit in a compact box like the 6400.
