Vertical refresh with VESA driver

Hi,

I have Mandrake 9.2 installed. Since my onboard VIA video isn't recognized,
it is using VESA driver.

I would like to know how can I get vertical refresh frequencies higher than
60Hz. My XF86Config-4 and XFree86.0.log files are attached.

I've tryied some modifications in XF86Config-4, like adding specific
ModeLines and changing options in Display Subsection, without success. The
one attached is the original from installation.

I've found in the log file lines suggesting that higher frequencies are
possible, like:
(II) VESA(0): Supported VESA Video Modes:
(II) VESA(0): 640x480@60Hz
(II) VESA(0): 800x600@75Hz
(II) VESA(0): 832x624@75Hz
(II) VESA(0): 1024x768@75Hz

But I can't understand the lines:
(II) VESA(0): Attempting to use 85Hz refresh for mode "800x600" (114)
(II) VESA(0): Attempting to use 85Hz refresh for mode "640x480" (111)
...attempting... and why not succeeding?

Thank you for any possible help.

Paulo
