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.
