I'm not sure how much this will help, but for what it's worth...

I'm running X with a Diamond Stealth 64 DRAM VLB card, 1 MB RAM. It has 
the S3 Vision 864 and S3 SDAC chipset. Whenever I have run xf86config, 
either that routine has run the clock probe (after asking permission), or 
has indicated that it shouldn't and has the data in the card database.

In any case, don't expect Xwindow to probe for clock lines when it runs; 
that info should already be in the XF86Config file from when you 
configured the system for the card. If not, and you don't have the 
necessary info, repeat the configuration process.
