Timer problem with bochs

I played with the PIT a bit, and I saw some problem with one emulator. Bochs get it all wrong.
Qemu and
Virtual PC shows the processes correctly, their messages at correct frequency, but
bochs is too fast. I just hope it's not a newbie error, but there's no shame if it is

Bochs tries to emulate as fast as possible, which is why the PIT is sometimes really fast and sometimes really slow.

adding this:
To your bochsrc puts it at a more reasonable rate. I still have reason to believe it's incorrect though (slightly too fast)

using
will slow down bochs to the correct speed. The realtime clock is only an approximation

Yeah, I had this problem a while ago... I don't know why it is the default timing!
