why X insist on using vesa driver?

[Yuwen Dai]

Dear all,

I have two computers installed Debian sarge.  One uses ATI readon 9000 and the other uses nvidia.  I uses dpkg-reconfigre xserver-xfree86 to configure X, then I found in XF86Config-4 vesa is used:

Section "Device"
        Identifier      "Generic Video Card"
        Driver          "vesa"
        Option          "VBERestore"    "true"
EndSection

Why?

Best regards,
Dai Yuwen
