No, it genuinely went from working to broken - it's
not a case of always being broken but never
previously being necessary. It broke first in RT
kernels, so I'm guessing it broke in mainline with an
RT patch merge.
I'm not aware of anyone these days successfully
using Rosegarden with snd-rtctimer - if anyone out
there is, do say so. Either you get a 1000Hz kernel
or you suffer with crap timing.

The most recent such report we had was from a
user of OpenSUSE 10.1 (with 2.6.16 I think?). I
suggested trying an ALSA driver upgrade; apparently it didn't help. The thread should be easily found in
the Rosegarden list archives by searching for rtc
and opensuse.
I don't have a computer here to test it on at all
myself at the moment, I'm afraid. I will do later. Honest.
