OK, it works with git 99f9f3d49cbc7d944476f6fde53a77ec789ab2aa
(something after -rc4). I can echo something into
/sys/class/rtc/rtc0/wakealarm and the machine will wake up from suspend
to RAM.

However, a minor glitch remains:

$ echo 1181672013 > /sys/class/rtc/rtc0/wakealarm

- suspend

- wait for wakeup

After wakeup:

$ cat /sys/class/rtc/rtc0/wakealarm
2051656909
