Well then, you should remove refresh rate selection on the command line 
if it's not available ;o)

My system is a NatSemi system (MediaGX1 w/ CS5530A), Vesa 2.0 compliant. 
I've succeded in changing resolution, but the driver does not seem to be 
so stable...
However , they ship a Xfree86 driver for their framebuffer, to allow 
acceleration through their framebuffer (also customized through the 
kernel). They say it work on Xfree86 4.0.1, though I havn't investigated 
much to make it work with current, thinking the framebuffer driver w/ 
standard Xfbdev would do the trick. Could you describe the easy way to 
integrate a new driver for kdrive ?
