6.2-PRE, AGP X800, and Modular Xorg == No DRI?

[Isaac Waldron]

Yongjhen,

Your patch worked for me.  This is the patch I applied to get
radeon_drv to report that it couldn't find drmAvailable:

+      return FALSE;

     if (!xf86LoaderCheckSymbol("DRIQueryVersion")) {
       xf86DrvMsg(pScrn->scrnIndex, X_ERROR,
 		 "[dri] RADEONDRIGetVersion failed (libdri.a too old)\n"
