Content preview: Use resource_size_t for physical address of SystemACE chip. This fixes the driver brokeness for 32 bit systems with 64 bit resources (e.g. PPC440SPe). Also this patch adds one more compatible string for more clean description of the hardware, and fixes a sector_t- related compilation warning.
