Daniel has a patch set that includes the following:

0010-OLPC-add-XO-1-rtc-driver.patch

+++ b/arch/x86/platform/olpc/olpc.c
@@ -311,6 +311,8 @@ static int __init add_xo1_platform_devices(void)
 {
        struct platform_device *pdev;

+       olpc_xo1_rtc_init();
+
        pdev = platform_device_register_simple("xo1-rfkill", -1, NULL,
  0);


This registers a specific rtc device for XO-1 machines (using the
CS5536 RTC).  XO-1.5 uses ACPI and a Via-based board, so the RTC device
should be handled there automatically.  The corner case is for machines
where the OLPC DT is enabled, but OLPC_XO1_RTC is not enabled.  We
still need to figure out what to do in that case, but I think it's more
appropriate to focus on getting the PM and XO1_RTC stuff upstream
first.  As of right now, it's the *only* case.  We'll change that, by
getting OLPC_XO1_RTC upstream.
