Please find small patch to linux-2.4.7 agpgart/drm for very popular
and powerfull VIA VT82C694X chipset ( Intel PIII/CII ).
Until now it was not directly supported by agpgart/drm in kernel
and for operation need ugly agp_try_unsupported=1 into modules.conf
If you interested there is also the second patch ( or you can put it
manually ) to XFree-4.1.0 drm/kernel
Is it possible to include it to in future kernels ?
