VIA VT610 IDE support for 2.4.28 (trivial)

hi,

I found an older version of this patch (against 2.4.22) on some website. 
After a little bit of editing it applied cleanly to 2.4.27 (and now 
2.4.28). It works fine for me on a ASUS P4P800-Deluxe with 4x 300GB disks.

Maybe someone finds this patch helpful. Any reason why the original 
patch did not make it into the kernel ?
