RTC-driver kernel 2.6.xxx missing Symbols

[Juergen Keidel <wizant.keidel@online.de>]

Hello,
The actual kernel has a new reworked rtc driving system. before, I think
2.6.5, the driver was rtc (rtc.c in drivers/char from  Paul Gortmaker,
which exported the function rtc_control, rtc_register, rtc_unregister.
These functions are very useful for drivers wich need acces to the rtc.
The new rtc-system (rtc-cmos) is missing these functions.
As I found out, some drivers especially within the sound area are using
the functionality, so they won't load anymore!
(sound/core/rtctimer.c)
Is there a way around with the new system or is it planned to reactivate
these functionality.
Actually, I have to rmove rtc_cmos and load the old rtc, to get my
drivers working.
One of the Systems I'm running:
