The references say that Rochester got "access to full design and test IP", which means they just need to produce/obtain new wafers in the correct process size (320nm in case of latest 68060 revision) and can then use the corresponding chip masks from Freescale/NXP for UV lithography.
They already list 68020 and 68040 parts as being Rochester-manufactured. Of course, these might still be produced from old-stock wafers. 68030 and 68060 parts still seem to be old Motorola/Freescale stock.
