I just downloaded the kernel and ramdisk files from the mirror, and the ramdisk is not the same size as what is listed in the Seagate DockStar Reflashing instructions. 11,770,457 versus 11,770,380 bytes. The kernel size matches (1,978,608 bytes).
No, don't do it. Every device has its own kernel and ramdisk and everything. I'd email Seagate asking for the kernels and ramdisk. They have released the recovery image for the GoFlex Home, so you might have luck getting the GoFlex Net images from them too.
