The result is that a couple of jumps are no longer possible for

With com_maxfps 125 I was able to make the jump, though I have
the impression that it got "trickier", i.e. more difficult to do it.
This was expected that some users will experience that problem. What is your
operating system and distribution? And most importantly: what is your system
Hz setting if there exists something like this?
Operating system: FreeBSD 8-stable development branch
Hz: according to xrandr 60
Some older Linux kernels will exhibit this problem. There is an easy
workaround: set cvar com_busywait 1 and it should revert back to the old
behaviour.
No Linux involvement here. Anyway, setting com_busywait works fine.
Once you've updated your system I expect this workaround will not be necessary
anymore.
The system is built from 12 days old development sources. Not
particularly outdated:
uname -a
FreeBSD mobileKamikaze.norad 8.2-PRERELEASE FreeBSD 8.2-PRERELEASE #0: Tue Feb
8 15:38:58 CET 2011
root@mobileKamikaze.norad:/usr/obj/HP6510b-8/amd64/usr/src/sys/HP6510b-8 amd64
Note that all that fancy new GEM, KMS and so forth mumbo jumbo is
not available on FreeBSD. So it might be that the video drivers are
somewhat dated, since the Xorg project has stopped caring about
portability.
Regards
GEM and KMS are coming to FreeBSD, see

Of course this doesn't help right now.
Maybe Thilo or somebody else knows what recent changes in Linux fixed
this (maybe it's scheduling-related?) and FreeBSD already has similar
stuff that just has to be configured accordingly?
Cheers,
