Your new RTC driver seems to work for me (thinkpad x60), but no, I
can't get wakeup using RTC to work:

root@amd:~# echo HDEF > /proc/acpi/wakeup
root@amd:~# cat /proc/acpi/wakeup

rtcwake: wakeup from "disk" using rtc0 at Sun Aug 27 16:54:49 2006
root@amd:~#

Any ideas? (I tried suspending to RAM, too; no change).

Is acpi-rtc code likely to be merged?
