Linux/mac68k has improved gradually over the last 5 years or so. 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.
