Yes. I'd recommend applying Ameet's patches at http://www.linux.get2knowmore.com/ however you will still need to change a few macro lines for the COMPACTFLASH addresses. There is also a major error in the board_info structure. Someone changed this data structure for the ml403 & ml300 so that it no longer matches the UBoot form. The one in asm/ppcboot.h is correct. Someone else asked about this back in June.
