I've commented this out as I can't find a way to make this number 'stable'.
For example ipmi_devintf module has ipmi_major parameter:

ipmi_major:Sets the major number of the IPMI device.  By default, or if you set it to zero, it will
 choose the next available device.  Setting it to -1 will disable the interface.  Other values will
 set the major device number to that value.

and thus can be bind forever, but I don't see any parameters for
rtc_cmos driver.

BTW why is it build into kernel not module? Thu Dec 4 10:12:40 2008 by pluto
- built-in rtc cmos driver.
