There were numerous bug fixes that may benefit your Macs and even some new functionality like /dev/nvram. For the LC475 there are still missing drivers (e.g. Localtalk and Apple Sound Chip) and unfinished drivers that don't fully exploit hardware capabilities, like SWIM and DAFB chips. Last year I replaced all the electrolytic capacitors in a pair of Quadras I use for testing. I recommend that you take a close look at your LC475 boards before putting them to work again. I still put stable mac68k kernel binaries on sourceforge from time to time. I will put up another one as soon as Al Viro's recent bug fix for arch/m68k/mm/fault.c goes upstream as it is needed on mac68k systems.
