the page cache is the one commonly referred to as block cache right (i.e. in the block layer, below the filesystem layer in the kernel)? what do you mean with disk write cache? the one where io commands are held so they can be reordered? I always thought that was the same as the block cache - and also hard disks sometimes do this themselves, buffering in a few megs of memory on the hard disk itself?
