agpgart & Via VT8605 [PM133] AGP

[Meelis Roos]

I recently installed Linux on a PIII/733 computer with Via PM133
chipset. Agpgart module loads only when used with agp_try_unsupported=1.
It seems to be stable so far (several 3d screensavers tested for half an
hour and some tracks of tuxracer), Ati R128 DRM. Kernel is 2.4.20-rc3.
