g400 vs vbehz

Hello,

I've got a g400, runs very well. Except the matrox utils
(vbetsr, vbesetup) don't work with g400's. But the card has
vesa 3.0, so I've tried using vbehz 2.23

Vbehz is able to raise the rates. But it never gives me the
rates I ask for. It's as though it can't do the math right, or
something. If I set it for (640*480,72.8 hz) I get strange rates
like (73.4hz) Same for all the other resolutions. I know the
card is able, because while in windows or os/2 the rates are
correct.

Any suggestions?
Thanks
