   Thats very helpful thanks so much

  .. while I'll be putting F14 on this - I'll be using newer kernels -
2.6.39 and 3.0 once the dust settles a bit more.

    I used gparted to partition it - and set alignment to cylinder tho I
wasn't sure if that was preferable to MiB alignment - any thoughts on
alignment ?
