How is the attached one for an updated
version? Please check the compilation
on arm as I haven't done that.

Recently (around 2.6.25) I've noticed that RTC no longer works for me.  It
turned out this is because I use pnpacpi=off kernel option to work around
the parport_pc bugs.  I always did so, but RTC used to work fine in the
past, and now it have regressed.

The attached patch fixes the problem by creating the platform device for
the RTC when PNP is disabled.  This may also help running the PNP-enabled
kernel on an older PCs.
