(I think these drives may already be available at least as engineering samples. Basic linux kernel support went in summer 2009 I believe. I believe 2.6.33 will be the first kernel to have been tested with these new class of drives.)
I purchased two WD20EARS drives yesterday, going to play around with them tonight. They emulate 512 bytes sectors to the SATA layer but write them as 4k on drive, so you want to make sure that everything that writes to the drive, writes in 4k block size (which is the case with most in linux as far as I have understood).
So basically they'll work with any OS, but for best performance you need to make sure that things are aligned to 4k boundary and you want to write 4k at a time.
