Generic PCI 64 or 66MHz interface chip availability?

[Austin Franklin <austin@darkroom.com>]

I did a design some time ago that used a PLX 9080...and it needs to be 
upgraded to a 64 bit or a 66MHz PCI interface...  Well, apparently PLX 
dropped the ball on 64/66PCI and they do not have a current offering that 
supports 64/66MHz.

Does anyone know of a vendor that offers a generic PCI interface with a 
similar back end/DMA engine to the PLX9080 that is 64 bit and/or 66Mhz (one 
or the other will do).

Thanks!
