The standard ATA IDE hardware supports only 32bit addressing. However if your I/O mapping logic is correctly implemented for the architecture that should cause no problems as the buffers will be bounced. The SIL680 hardware actually can support 64bit DMA using a private non-standard PRD format and the data sheet is available if someone wants to do the work. Probably best to do it for the new libata driver but its doable for either
