[reposting from -hackers as i found this to be the place where
emulators/rtc has been discussed previously]

Hi!

Is the following patch to the emulators/rtc port right? qemu
(ports/emulators/qemu) expects it
to send SIGIO and i'm not that good at kernel hacking to know
if the following is correct... it seems to work for me tho.

(Anyone interested in helping fixing the other problems mentioned
in the pkg-message is welcome also. This looks like a coool project...)
