[Dri-devel] Patch to agpgart and XFree-4.1.0 drm/kernel for VIA Apollo Pro 133A - VIA694X chipset

[maciek n <mac...@wp...>]

Please find small patch to linux-2.4.7 agpgart/drm and to XFree-4.1.0 
drm/kernel for very popular and powerfull VIA VT82C694X chipset ( 
Intel PIII/CII PC133 ). 

Until now it was not directly supported by agpgart/drm in kernel
and for operation need ugly agp_try_unsupported=1 into modules.conf
