Collect together the components of several drivers and export eisa from the i386-only area (It's not, it's on some alphas too). The code hasn't been updated to work on the Alpha yet, but that can come later. Repository copies were done a while ago. Moving these now keeps them in consistant place across the 4.x series as the newbusification progresses. Submitted by: mdodd
