 Hi Simon,
  the proposal actually had a fully-working patch attached :)

 In my code, the first rtc that register is bound
 to /proc/driver/rtc and /dev/rtc (if those interfaces
 are compiled in, as they are all selectable).

 The other RTCs are available thru /sys/class/rtc/rtcX
 (again, if compiled in).

 You have full control of which functions you will provide
 to the upper layer. Obivously if you try to set the
 time on a read-only rtc, you will get an error.

 Thanks, I'll consider it if the need arises.
