[Cooker] harddrake and disk

[pgeorges]

When clicking on 'configure' in harddrake->disk, the partition tool
comes up. I think a way of setting DMA, 32bit access and so on for a
disk would also be nice (I have to put my hdparm tuning parameters into
rc.local, unless I missed another better way ? ).

I checked 'use hard drive optimisation' during cooker's installation but
my hard drive was less than optimised (no 32 bit, no UDMA66, ...).
