Now this is something that deserves investigating. As far as I know,
the libdirectfb library that we use for Splashy, doesn't try to
manipulate those settings unless you explicitly tell it to do so.

One more thing, your card does support 95Hz, right? It's just that
your monitor can't handle it. We do have code in Splashy that looks
for the highest resolution supported by the card and uses that.
However, I was under the impression that if you set the limit with
your kernel parameters, that libdirectfb would not be able to go
higher than that. I'm guessing that in the case of matroxfb, you are
setting your default rate to 75Hz, but the card can go higher at any
point. Perhaps Splashy needs a configuration in
/etc/splashy/config.xml to tell it up to what resolution it should be
attempting to work.

I'll add this to our TODO file for investigation. Though it will be
hard for us to reproduce your setup. We all use vesafb since that is
known to work flawlessly.
