Strange that it has been disabled, I used to keep an eye to avoid touching
anything outside of drivers/rtc .

the rtc subsystem creates the device dynamically, you shouldn't count
on having 254,0. I would eventually ack a patch that adds
/dev/rtc at 10,135 as an alias for /dev/rtc0.

however the best solution would be to upgrade hwclock.
